Simple expression error

[Luuk Arts]

I’m fairly new to writing my own expressions in After Effects. That said I can’t seem to figure out why this line of code isn’t working.

Must be something I’m just missing..

Thanks in advance!

The newer Javascript expression engine is more strict than the legacy extendscript engine. if/else statements cannot be on a single line. Try this instead:

if(thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider") ==  5) {
100;
} else {
50;
};

I’ll note that you can change the expression engine you’re using by going to File>Project Settings and then picking the “Expressions” tab.
