[LUA] [ERROR] attempt to call string

I'm making my own api and am trying to create a function that displays all the stuff in a turtles inventory in a gui fashion:

function invPrint()
slot1 = tostring(turtle.getItemCount(1))
slot2 = tostring(turtle.getItemCount(2))
slot3 = tostring(turtle.getItemCount(3))
slot4 = tostring(turtle.getItemCount(4))
slot5 = tostring(turtle.getItemCount(5))
slot6 = tostring(turtle.getItemCount(6))
slot7 = tostring(turtle.getItemCount(7))
slot8 = tostring(turtle.getItemCount(8))
slot9 = tostring(turtle.getItemCount(9))
print("=============")
print("|   |   |   |")
print("| " .. slot1 .. " | " .. slot2 .. " | " .. slot3 " |")	 //error
print("| " .. slot4 .. " | " .. slot5 .. " | " .. slot6 " |")
print("| " .. slot7 .. " | " .. slot8 .. " | " .. slot9 " |")
print("|   |   |   |")
print("=============")
end

When I ask it to start printing the actual numbers [print("| " .. slot1 .. " | " .. slot2 .. " | " .. slot3 " |")] the code returns an attempt to call string error, I am not sure why this is happening as the print function works with strings, does it not? Any help on this matter will be much appreciated.

My guess would be that you've overwritten one of the functions with a string.

What line number are you erroring in?

you mean in the whole api or on that one section of code?

The line # for the whole API wouldn't help me much, as I still wouldn't know which line was causing the error.

He he, sorry, good point. It is line 13.

im not sure, but don't
you need to put it like this

" ..slot3.. "

instead of

" .. slot3 "

Please note, that i "suck" at Lua :b

I see the error now; you forgot the concatenation operator:

print("| " .. slot1 .. " | " .. slot2 .. " | " .. slot3 " |") -- Missing last .., same with lines below  
print("| " .. slot4 .. " | " .. slot5 .. " | " .. slot6 " |")
print("| " .. slot7 .. " | " .. slot8 .. " | " .. slot9 " |")

Should be:

print("| " .. slot1 .. " | " .. slot2 .. " | " .. slot3 .. " |")
print("| " .. slot4 .. " | " .. slot5 .. " | " .. slot6 .. " |")
print("| " .. slot7 .. " | " .. slot8 .. " | " .. slot9 .. " |")

Also, note that comments start with a – in lua, not // like some other languages.

my bad, and ahhhhhhhhh, tut stupid minor mistakes, thank you :(/>/>
