Help with setting up scenario to return query results from SeaTable to Fillout via Make

Hello everyone, I’m new to Make and finding it challenging to complete my 1st scenario which users a search field in a Fillout Form to capture the search text to be submitted via Make to a SeaTable table AND then return the results obtain from a successful search to another Fillout Form as a Redirect using URL parameters.
I’ve got the first part working OK (Fillout-Make-SeaTable) but am struggling to define the rest of the scenario. I know that I’ll need a Router Module to branch between Success and Failure for the search but when I attempt to add a new Module to consume the search results for the Success branch and push these back to Fillout as a Redirect, I’m unable to select Fillout again - I assume I’m missing something simple but any pointers in the right direction would be much appreciated. Equally I need to understand how bes to alert the submitter to a Failure - any suggestions as to the best way to do this? David
