### Issue Priority

Priority: 3

### Issue Component

Component: Actions

Start by inspecting the samples project and the existing samples for the checked actions: Check Db connections, Columns exist in a table, End Repeat, JavaScript, Repeat, Table Exists, and Zip File. Work through the unchecked action list, and consider the task done when each action has a corresponding sample in the project.
