JotForm Automation

I need 3 automations in JotForm all based on a Google Sheet:

1. Disable or Enable a JotForm based on a cell value in a Google sheet

2. Change the data of a drop-down on a JotForm based on a cell value in a Google Sheet

3. Conditional logic in a JotForm based on a value in a Google Sheet - e.g if. A cell value returns “full” the conditional logic in the JotForm should send the user to a different page in the form
