The url that you need to change is the one in the custom code block that loads the tally form into softr.
@dcoletta thanks for the guidance and link to Tally help. I suspected custom code (on Softr side) was required to grab the value(s). I’m a product person, not dev, so I’ll request help from a Softr expert (or perhaps find a code snippet somewhere). Appreciate pointing me in the right direction!
