for loop is only able to run once?

I have a for loop designed to test if the user's input, matches an entry in a table. The for loop I used is shown here:

local list = { [2] = "value1", [6] = "value2"}
local foundvalue = false
local uservalue = io.read()

for key,value in pairs(list) do
if value == uservalue then
foundvalue = true
else
–nothing is supposed to go here
end
end

if foundvalue == false then–executes code at the end of the for loop if it has not found the value
–blah,blah,blah

the for loop works great, but only once. The next time I try to activate it from a function, it doesn't seem to want to run.

Any ideas?

It'd be best if you posted the full code. The code above doesn't seem to be prone to errors.

Also, use [​code][​/code] tags.

print("They make things more readabe.")

hold on a sec. I think i found something

WOW! I've got to stop posting on the forums to early. I needed to put this:

local list = { [2] = "value1", [6] = "value2"}
local foundvalue = false
local uservalue = io.read()

foundvalue = false
for key,value in pairs(list) do
if value == uservalue then
foundvalue = true
else
–nothing is supposed to go here
end
end

if foundvalue == false then
–blah,blah,blah

it needed to set foundvalue back to false so that if it could run again. Sorry for the trouble.

Also by using

 tags, does that put it into code form?

Yeah, that's something I couldn't have noticed. I couldn't tell whether foundvalue was local to the function or not. I guessed it was but, apparently, it wasn't.

Nice catch, though. Solving it yourself, that is.

Yeah. That usually happens. I post and then find the problem

Thanks for trying to help me. Appreciate it :)/>

Oh, and yeah, code tags do that. Just don't copy the one I used for showing it; it's escaped.

[​code]print("you type stuff here")[/​code]

and you get

print("you type stuff here")

Unfortunately they cannot be used inline.

For inline code, set the font to monospace.

Also if you post intend your code
Edit: Actually always intend your code it will make it WAY easier for you to read

local list = { [2] = "value1", [6] = "value2"}
local foundvalue = false
local uservalue = io.read()
for key,value in pairs(list) do
if value == uservalue then
foundvalue = true
else
--nothing is supposed to go here
end
end
if foundvalue == false then--executes code at the end of the for loop if it has not found the value
--blah,blah,blah

vs.

local list = { [2] = "value1", [6] = "value2"}
local foundvalue = false
local uservalue = io.read()
for key,value in pairs(list) do
  if value == uservalue then
	foundvalue = true
  else
	--nothing is supposed to go here
  end
end
if foundvalue == false then--executes code at the end of the for loop if it has not found the value
--blah,blah,blah

Indent*

Edit: Indented code probably looks like this:

local list = { [2] = "value1", [6] = "value2"}
local foundvalue = false
local uservalue = io.read()
for key,value in pairs(list) do
    if value == uservalue then
        foundvalue = true
    else
        --nothing is supposed to go here
    end
end
if foundvalue == false then--executes code at the end of the for loop if it has not found the value
    --blah,blah,blah
end -- before, you had a missing end

Not this:

local list = { [2] = "value1", [6] = "value2"}
local foundvalue = false
local uservalue = io.read()
for key,value in pairs(list) do
if value == uservalue then
foundvalue = true
else
--nothing is supposed to go here
end
end
if foundvalue == false then--executes code at the end of the for loop if it has not found the value
--blah,blah,blah
end -- before, you had a missing end

You know what I mean. I have no idea why the code is not indented for you. I actually did indent it.

I'd imagine if you indented using tabs that they were removed.

I used two spaces to indent.
