If/Then statement error: Invalid token else

Question

I'm wracking my brain trying to fix this basic if/then expression. I have a text layer(name "Position (l/r") whose value I want to control the opacity of other layers. I'm using this expression on the layers whose opacity I want to control and applying it to the Opacity property:

if(thisComp.layer("Position (l/r)").text.sourceText=="r")100 else 0;

AE gives me the following error:

SyntaxError:Unexpected token else

I've used the exact same if/then expression format in other projects (only changing the layer name) and it works fine. I've copied this expression into another project and it works fine. If I copy the expression from a working project into the current project, it doesn't work.

I'm using AE 16.1.1.1 on Windows 10.

this because the new javaScript engine in AE CC 2019,,

you have 2 option to fix this, you can run the legacy ExtenScript from project settings

Or put the if/else value inside curly bracket like this { 100 }else{ 50 }
