Multiline Custom Photo Name not working

[ChrisJRoss13]

I am trying to set the filenames for a multiline image question.

I am using a date question (DateOfInspection). I created two calculate types: the first is ImageDate set as format-date(${DateOfInspection},"%Y%m%d") and the second is ImageIncrement as count-selected(${InspectionPhoto})+1. My bind::esri:parameters expression is fileName = concat(${ImageDate}, "_Inspection", ${ImageIncrement}).

I have tested the individual parts of the expression and they work but when I test, the image name formatting is not working.

Can you upload the xlsx?

My guess is that you are trying to concatenate a date field with a number field. Convert both to text in another  field, then concatenate the text.
