true not true?

Title: true not true?
I have a program that uses touch monitors and has user input and when i check if the user and pass is valid it returns true but when i put
if isValid then
do stuff
end
it registers isValid as false even though I have the prev. line saying that it is true(term.write(isValid))

Let us see your code.

Are you sure it is not "true", as in a string?

Even if this were the case, it would work, since he's saying he's using `if isValid then`, not `if isValid == true then`. I suspect a typo in isValid resulting in checking a nil value, or some sort of scoping issue. Obviously, without code, I can't be sure.
