Trying to hide fields based on dynamic dropdown entry

Trying to hide fields based on dynamic dropdown entry

Somewhat new to Creator and Deluge.

I have a dropdown field in a subform.  It allows the user to pick a "Town".  Based on that choice, I may want to hide most of the rest of the fields in the subform.  If the user picks an actual town, they then go on to choose a route, a client, etc.

If they choose "down time", I want to hide the remaining fields except for "End time".

For the life of me, I can't do this.  The problem is based on the value of the choice they made in the "Town" dropdown field.  Zoho shows it as a bigint but I can't seem to pull the value of that field as Zoho stores it.

Gosh, I hope this makes sense!  I having a lot of trouble finding good documentation... seems like it's all over the place.
