Wordpress / Gravity forms expert needed for quick consultation

The easiest £30 you'll ever earn... If you know what you're doing!

5 minute phone/zoom/teams call required to help me solve a stubborn challenge on Wordpress / Gravity forms / Populate Anything.

I'm trying to create a numeric total, based on a dynamically populated list of numbers... As both fields are dynamic, I can't use the calculations function, so the answer probably lies somewhere in the value template or a plugin that I've never heard of.

I'll share my screen, you offer me a solution. The money's yours. That's it!
