how do I implement text animation into an existing score sys

Hi,

I'm trying to insert animation text on a score system.. In attach you can see the CAPX

like most of games out there the idea is to add let say 100 as a rewarded video outcome to an existing score variable.

Id like to have an animation text after the click on bouns 100

Probably i need an expression in it, but I can't figure out how to do it

can anyone help please?

thanks
