**tbooroff**Hello

In the screenshot below, is it possible for JotForm to add up the hours circled in red and put them in the Total Hours box circled in blue?

Also, is it possible for JotForm to convert this total hours figure from hours and minutes into a decimal, e.g. 22 hours 45 minutes = 22.75 hours?

Thanks for your help!

**Welvin**Hi Tom,

Unfortunately, calculation feature doesn't support time field yet. Check our Calculation feature guide for supported fields: How to perform calculation in the form?

Thanks
