I am unable to Evaluate a boolean Expression within a variable.

(Craig, I can't find the code tag)

My code:

The contents of the TransposeOutputlogic is:
InputTable[3] and ((InputTable[0]) or (((InputTable[0]) or (InputTable[0])))) and InputTable[1] and InputTable[2] and InputTable[4]

-------- Does Not Work ----------
Code 1
if TransposeOutputlogic = true then
answer "Yes"
end if

-------- Works ----------
Code 2
if InputTable[3] and ((InputTable[0]) or (((InputTable[0]) or (InputTable[0])))) and InputTable[1] and InputTable[2] and InputTable[4] = true then
answer "Yes"
end if

Why is the Boolean expression within my variable TransposeOutputlogic not working?

Thanks,

David

So TransposeOutputlogic contains/results in FALSE?

Molto misterioso!

Will have to think about it, but try to resolve all those parens first.

I finally got it.

---- Works ----

Code: Select all

   if the value of TransposeOutputlogic = true then
     answer "Yes"
   else
     answer "No"
   end if

I had tried the code below but instead of "Value" I used "Val" and it gave me an error. That is when I reached out for help.

---- Does Not Work ----

Code: Select all

   if the val of TransposeOutputlogic = true then
     answer "Yes"
   else
     answer "No"
   end if

Thanks for everyone's time,

David

I see that you assumed "val" was a synonym for "value". We see it is not.

LC would have thrown an error, since it interpreted:

Code: Select all

 if the val of TransposeOutputlogic = true then

as if "val" was a custom property of "TransposeOutputlogic". But you cannot assign a custom property to a variable, only to an object.
