From top of my head.. you are evaluating a string channel by using CHS… you should use CH to evaluate an value

And make sure you keep the types in sync.. mix floats with floats, ints with ints… etc..

A couple thoughts occur to me, but as the frame # isn’t obviously a different parameter I’m not having any luck. In maya I might simply decouple the frame value from the default time expression and set keys, or do a +/- expression.
