Can anyone lend a braincell? 
Using bubble.io multi-file uploader for images (.png, .jpg, .svg, .jpeg) & files (.pdf, .ppt, .doc, .xls).
I’m using a “When muli-file uploader’s value is changed” workflow action to set the state to a group’s custom state’s, 1 state for images (list of), and 2nd state for files (list of). Then using those states as the data source for 2 repeating groups (RGs), each RG for the images vs file type extension. My problem is using a filter or constraint to get a yes/no on the custom states in the workflow to decide whether an uploaded file belongs in the “images” custom state vs the “files” custom state so the repeating groups on the page can show only the lists of their respective type. I read RegEx would work, but I can’t do it.
It’s for a chat messaging box, so I feel as if I could get away with 2 RG’s for now, but I’m sure some will say 1 RG is better, but my problem is still in the way of that.
Here’s screenshots of my workflow:
