citect scada Process Analyst

Hi, i hope you are well.

I cannot transfer a variable trend tag to the Citect scada Process analyst screen. The function I use is Asspopup("!ProcessAnalystpopup", "Tag1")

Tag1(defined Tag). Tag1_TREND (defined trend tag) 

In short, I want to transfer the tag to the trend screen with a function that I will define into a numeric display, how can I do this.
