I am new to DFFS (savvy Infopath/SP user); but I am trying to create a cascading dropdown with data from 1 list, which is using external data, connected to SQL (the data is being refreshed/updated, hence the BCS connection). Using the Cascading Dropdowns tab, I can create 1 drop down successfully. When I add the 2nd field, I get the error message “field name is incorrect” (internal name was correct). I’ve trouble shot by, making my 2nd (failed) drop down, as the first/only (works). I swap the order of the fields (fails – then the first “field name” fails with same message). I tried creating it manually using the installation guid instructions and using Custom JS (fails). My SP is 2013, and I”m on FFS v4.x Thank you for any insight!
I went back to get the screen shots, and entered my 2 fields again, and it actually SAVED. I referenced back to my notepad of the fields I used last night (didn’t work) vs now (worked) was that for it to work, it had no spaces in both the Comma separated fields. Thank you!
