Need help to create a skip logic tied to a date

I need help to create a skip logic that let a group of question appears only after a date (called base_date) is entered
Date and questions are in the same form (and question are all in the same Group).
I tried two different ways (in the design tool) to set the control of the skip logic:

  1. base_date != ""

  2. (after creating a calculate item "cross_base_date" related to base_date) cross_base_date was answered

but neither worked

I already use cross rules to check date between different forms, with no problem: I can't understand what Im doing wrong

thank you

Are you able to attach your survey form file here (with what you've tried so far)? That will help us troubleshoot. If you are using ODK Build, you should be able to save it as an XLSForm file.
