Oh wow.I did it! Not exactly i wanted but it works😀

fps=1.0/thisComp.frameDuration;

temp = thisComp.layer(“Text_Suchbegriff”).text.sourceText;

frameInterval = 3;

f = timeToFrames(time-1.5)

k = fps * frameInterval;

x = temp.length;

y = 100/x

s = y/2

value = (f*s)/frameInterval

Hi Dan! Thanks for feedback.How i understood i need to change value of selector every 3 frames to add a half opacity of new letter.I worked with expressions like this and i didnt find anything about it in internet.

Thank you for your help!
