ok after many bad result trying to solve this i could not get it work

problem is storing the variable in the expression for the next frame my code is simple like this applied on opacity

on frame 0,1 the x will equal to 10
however on frame 2 their is no x so what to do


note : the code is just testing and simplified i need to store result of calculation and use the result as input or to make it constant

Expression data does not persist from frame to frame. If you need data from a previous frame, you have to regenerate it. If you can base all your calculations on comp time, then it's pretty easy. Sometimes though, you end up having to recalculate frame-by-frame, starting at time = 0.
