What are Scalar properties?

Thanks everyone for the replies! You’re right I was just mistyping my code.

Thanks for your reply!

What I wanted to do is have some sort of way of instant hover effect. (for tekst highlights in an OS) If I just do linear it will gradually become visible and invisible. I want it to be a hard transition.

I got it from a youtube channel, and for him it does seem to work with this code which really boggles my mind.

Therefore I…

linear(a,0,1,0,100);

the error I get is as follows

error: argument 1 of linear() has to be scalar

I have written this expression to make a hover effect.
