Thanks! I tried this with a label on your Practice Form "First name:" with just the partial match name (see screenshot below):
However when I reload the Practice Page, the value "John" does not populate into the corresponding field below:
Do I need to do anything special for field labels that have spaces within the string? If I use just the (Form field) Name as "First" then it populates the value. Actually after playing with this some more it seems that it doesn't like the colon ":" for some reason in the Name field. Is that true? Thanks again, I'm getting the hang of how to use the tool now!
