Re: Expression problem, I need to understand why

[Erick Wilczynski] "Sorry. Here is the expression X = effect("Checkbox Control")("Checkbox") if (X = = 0)0 else (effect("Particular")("Particles/sec"))"

You have to separate the different operations with semi-colons like this:


X = effect("Checkbox Control")("Checkbox");
if (X == 0) 0;
else (effect("Particular")("Particles/sec"));


Also, I'm quite sure that you'll need the == operator without any spaces in between the ='s. == (comparison) is a wholly different operator than = (assignment) and two ='s separated by a space may be seen as two assignment (=) operators instead of one comparison (==) operator.
