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 [code] tags, does that put it into code form?

[LBPHacker]

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.

[Varscott11]

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

Thanks for trying to help me. Appreciate it

[LBPHacker]

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.

[KingofGamesYami]

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.
