Let's say you've got a table, and you don't know what's in it. I usually respond by iterating through it and printing the contents:

for key,value in pairs(someTable) do
  print(key.." is a "..type(value))
end

Say you build this table:

local someTable = {43,{345,345},"SDFsf",3453,["somekey"] = "sdfsdf"}

If you ran the above code under that, it'd print something like this:

1 is a number
2 is a table
3 is a string
4 is a number
somekey is a string

That'd tell you that your table looks like this:

someTable[1] -- A number
someTable[2] -- A table
someTable[3] -- A string
someTable[4] -- A number
someTable["someKey"] -- A string

So if you wanted to print the string in someTable[3], you'd just do:

print(someTable[3])

And if you wanted to see what was in the table in someTable[2], you'd do:

for key,value in pairs(someTable[2]) do
  print(key.." is a "..type(value))
end

… and so on.

local tankInfo = getTankInfo() --#Change the GetTankInfo to what you use for it.
for key,value in pairs(tankInfo) do
  print("Use " .. key .. " to reference " ..value) --#This will tell you what variable to use to get the information, and the information itself.
--#You would want to use tankInfo[ whatever key you got ] to get the value at that spot.
--#If for instance a table looked like this tablename = {key1 = "cake",42} calling tablename[1] would give you 42, and tablename["key1"] or tablename.key1 will give you cake
--#If you don't supply a number or name infront of it, it starts at 1 and continues on for each one that doesn't have a key.
end

i tried printing (for good manners) the getTankInfo table and got the folowing
"table: 300204d8"

which i have no idea what means..

lava1 = peripheral.wrap("rcsteeltankvalvetile_0")

lava1info = lava1.getTankInfo("unknown")

print(lava1info[3])
 
for key, value in pairs (lava1info) do
 print(key.." - "..value)
end

print(key.." - "..type(values))

At least one of the values in lava1info is another table.

You can't combine text such as " - " together with a table, hence the error message.

You could use this instead:

print(key.." - "..type(values))

That way, you'll at least know the key names, along with the types of data they have attached to them.

for key, value in pairs (lava1info[1]) do
  print(key.." - "..type(value))
end

What it's telling you is that there are two entries in the "lava1info" table. One has a key of 1 (and can hence be referenced as lava1info[1]). The other has a key of 2 (and can hence be referenced as lava1info[2]). Both of these entries have another table assigned to them.

So let's say we want to know what's in the lavainfo[1] table. We'd run this:

for key, value in pairs (lava1info[1]) do
  print(key.." - "..type(value))
end

print(lava1info[1]["capacity"])

What it's telling you is that there are five entries in the "lava1info[1]" table. One has a key of "Raw name" (and can hence be referenced as lava1info[1]["Raw name"]). Another has a key of "amount" (and can hence be referenced as lava1info[1]["amount"]). Etc, etc, etc…

So let's say you wanted to print the capacity. You'd do this:

print(lava1info[1]["capacity"])

lava1 = *wrapping here*
lava2 = *wrapping here*

local function lava()
  lava1info = lava1.getTankInfo()
  lava2info = lava2.getTankInfo()
  lava1am = lava1info([1]["amount"])
  lava2am = lava2info([1]["amount"])
  lavatotal = lava1am + lava2am
  lava1cap = lava1info[1]["capacity"])
  lava2cap = lava2info[1]["capacity"])
  lavacap = lava1cap + lava2cap
  lavapercent = math.floor(lavatotal / lavacap * 100)
end

lava1info([1]["amount"])

lava1info[1]["amount"]
--#Or you can use
lava1info.1.amount --#Although i'm not sure if it works with numbered keys.

return math.floor(lavatotal / lavacap * 100)
--# Instead of
lavapercent = math.floor(lavatotal / lavacap * 100)

No. You are calling them as if they're functions. You do not want to use

lava1info([1]["amount"])

And should instead use

lava1info[1]["amount"]
--#Or you can use
lava1info.1.amount --#Although i'm not sure if it works with numbered keys.

Also at the end, you need to return the value rather than keep it inside the function (if you kept it all local :P/>)

return math.floor(lavatotal / lavacap * 100)
--# Instead of
lavapercent = math.floor(lavatotal / lavacap * 100)

Also i do believe i gave you a link to variable scope, it's easy to employ :P/>

local fakeTable = {"hi", [2] = "yaaaay!", "ddddddd",Keylist = "HEHEHEHEHE"}

local fakeTable = {[1] = "hi", [2] = "yaaaay!", [3] = "dddddddd", ["Keylist"] = "HEHEHEHEHEHE"}

print(fakeTable[1]) --> "hi"
print(fakeTable[2]) --> "yaaaay!"
print(fakeTable[3]) --> "dddddddd"
print(fakeTable["Keylist"]) --> "HEHEHEHEHEHEHE"

local multiTable = { { "Hi",Keyed = "Bye"}, secondTable = { "My second table rocks :D/>",Noo = "No it doesn't..."} }

local multiTable = { [1] = { [1] = "Hi", ["Keyed"] = "Bye"}, ["secondTable"] = { [1] = "My second table rocks :D/>", ["Noo"] = "No it doesn't..."} }

print(multiTable[1][1]) --> "Hi"
print(multiTable[1]["Keyed"]) --> "Bye"
print(multiTable["secondTable"][1]) --> "My second table rocks :D/>"
print(multiTable["secondTable"]["Noo"]) --> "No it doesn't..."

mon.write("Lava amount: "..lava.."%")
--# Should be
mon.write("Lava amount: "..lava().."%")

lava2cap = lava2info[1]["capatity"]
--#Should be
lava2cap = lava2info[1]["capacity"] --# You mispelled :P/>
