Expression Error

[Ayosmart]

I'm trying to create an expression where th circle will scale relative to the slider control, but it keeps giving me errors, says linear needs 3 0r 5 arguments

I don't think you need linear(), so it would just be:

mScale = Math.round(thisComp.layer("Settings").effect("Slider Control")("Slider"));
[mScale,mScale]
