How to get a list of custom form issue fields (Project) on a Task report?

Hi all -

I am reframing a previous question based on need (I originally asked for counts). We use Task reports a lot to push our work queue forward. We are utilizing "issues" to hold itemized data from our old system using a custom form. How do I get a list of all issues on the Project to show up in these Task reports? I am looking for 1 or 2 custom form fields - 1 per column - to be listed.

I've seen similar threads here but I tried and tweaked all of the text mode code and nothing actually worked. I'm still pretty new at text mode, so does anyone have any idea what to include?

The fields are:

DE: VT Migration HiRes Filename

DE: VT Migration HiRes File Path

Thank you!
