Hi @lmooring, As of July 12, 2018, Caspio introduced new features which you can find here: https://howto.caspio.com/release-notes/caspio-bridge-13-0/ This release includes a new feature, Calculated Values in Submission Forms.  This allows you to generate calculations which you can use for your date using Mathilda's DATEADD(dd, 1, [@field:end_date]) and then submit/insert it to your table without using JS.
