After Effects Expressions Help

[Massimo]

Need some help with Expressions in after effects.

This is what I have but dose not work

thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider") if (Both Channels < 1) 0 else .value

What I want to do is have the effect to only take place when "both channels" are greater than 1. Once greater than 1 I want the effect to reference the key frame value by using .value

I am pretty sure that if and else expression is what I need I just don't know how to use it.

I know AE - been a long time singe I've used expressions. What effect are you trying to pull off?

Never mind figured it out

thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")
> 2 ? thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")/4:0

I am creating a glitch to match some music problem was that the key frames all had some value to them so the whole video was glitchy.

I was able to use some adjustments to amplify there areas that needed the glitch, then I just needed to create and expression for the effect to only become active over a certain value.
