Error with opacity expression
Having an error with this opacity expression in CC2019:
opacityEven = 50;
opacityOdd = 100;
f = timeToFrames();
if (f%2 == 0) opacityEven else opacityOddMessage:
After Effects warning: Expression Disabled
Error at line 1 in property ‘Opacity’ of layer (‘xyz’) in comp
‘xyz’.Undefined value in expression (could be an out of range array subscript?)

That single-line if/else syntax won’t work with the new JavaScript engine. Try changing the last line to this:
(f%2 == 0) ? opacityEven : opacityOdd

Hi Dan, I tried that exact expression and got this error:
ReferenceError: f is not defined

Did you replace just the last line? The whole expression would be like this:
opacityEven = 50;
opacityOdd = 100;
f = timeToFrames();
(f%2 == 0) ? opacityEven : opacityOddDan

My bad, I just replaced the last line and it now works. Thank you so much!
