Thanks for getting in touch with us. I think you’re on the right track, but there are a few extra steps that you’ll need to do to get this working 100%. First, make sure that you rename the target comp you want to swap. When a comp is first dragged into the timeline, the name will be surrounded by braces (i.e.: [Shapes PC]). If Templater is applied to a layer with this naming convention, it’ll only be swapped out once. This goes for images, movie files, and other assets to be switched out as well. So I’d definitely start by renaming the comp. You may also need to put double curly braces on the comps you want to cycle through in the data set. So rather than precomp1, precomp2, etc maybe try {{precomp1}}, {{precomp2}}, and so on. Give those suggestions a shot and if you run into additional issues, please just let us know. Thanks!
