Hi,

I have a scenario where there are two list fields, Start Time & End Time in a table

There is a field called Total.

The Start Time has entries at increment of 5 minutes like: 8:05, 8:10....17:05, 17.10

Same is for End Time: 8:05, 8:10....17:05, 17.10

Every row has these with a Total field at the end of the row.

What I want is if the user selects 8:05 in Start Time & 10:30 in End Time, the Total field should show the value as time worked, in this case 2 hours & 25 minutes.

I am not sure if this can be achieved by using formula or javascript?

Can someone please help? 

Regards,

Sahil
