Form Calculations: Calculate time shift and hide the other questions.

What I am looking for: if submitter enters their start shift and end shift times, and the calculation of the difference is less than 15 hours, the remainder of the questions hide and a statement displays instead reading “your shift hours do not permit a nap”. Cancel submission.

If they enter their start shift and end shift times, and the calculated difference is 15 or more hours, the remainder of the questions display and they can submit the request.

Hi Sandy,

Thanks for reaching out to Jotform Support. I suggest using Form Calculations and Show/Hide Field Conditions. Let me show you how to do it:

1. In your Form Builder, go to Form Elements on the left side of the screen.
2. Select the Time to add it to your form.
3. Click Properties.
4. On the Time Properties, select Range.
5. Click the Toggle Button to enable the Time Range.
6. Select the Toggle Button to enable the Duration Indicator.
   
7. Next, click Widgets.
8. Select Form Calculation to add it to your form.
9. Click the Wand Icon to go to Widget Settings.
10. Select Add Field and click Time Shift.
    
    
11. Go to Form Elements again to add the Paragraph.
    
    
12. Now, go to Settings.
13. Select Conditions on the left.
14. Click Show/Hide Field.
