How to calculate the total of different time fields and use it in calculation?

Hi, How do I use the calculated time duration from the time field as the basis for my form calculation field? Currently, If I select the time field for calculation in the form calculation widget it gives me a response of zero. But I would like to add all the days' durations to give me a weekly total I can use to calculate my weekly rate. How can I make this possible, please on page 5?

If I understood your question correctly, do you wish to calculate the total time of the 3 time fields in the screenshot below and multiply the total sum with 3600?

To achieve that you can just add the below formula in the calculation widget.

Hi on the Monday example, I used the 24-hour clock so that the duration would be calculated. I need to add the durations from what will be the 5 days of the week and use this for my calculation- Selecting Monday 0-9 currently gives a return of zero, I cannot figure out how to access the calculated duration field so that I can use it? Is this something that can be done?

To clarify, do you want to calculate your time field?

I have checked your form and it seems the calculation work correctly.

Can you please explain further how you want to calculate the time field with your form?
