I work on a project and i will describe it in deep just to gave you the critical point wich have stucked with it.
I make an string (text layer) of numbers (1 2 3 4 ...... 9 ) and i connected with the slider control so the user can dynamically change the value of the string depending on the value of the slider...
then i want to make a first keyframe at 0:0 for example, then i want the second value wich the user also can dynamically choose be on the other keyframe for example at 0:2 (after tow seconds)
how i can write an expression to do the 1st and 2nd keyframes dynamically without any human action ??
i hope you can understand my issue correctlly.
