I have a simple question that is not so simple to describe.

I have a database that tracks production for my cabinetshop.

This database has a calculation field (TOTAL MINUTES) that subtracts one timestamp from another to tell me how long things take to build.

I have recently added a QUANTITY field and would like to to divide total minutes by quantity in order to produce MINUTES PER ITEM.

TOTAL MINUTES is a timefield.

Whenever I divide this timefield by a numeral the result shows up as a (?) question mark.

Can anybody advise me how format one of these fields to get to a decimal result?

Thanks for any insight,

Jarvis

Make TOTAL MINUTES a number field. It doesn't represent a time, it represents a number of minutes.

Minutes Per Item should be a calculated field.

MinutesperItem = Total Minutes/Quantity

Set calculation to a Time field.

That should give you average amount of time in hr/min/ss.

Thanks guys.

I was able to get it to work with the a calculation field.

[(stop time - start time)/60] ÷ Qty

Start time & stop time are timestamps.

The calculation result was set to display as TIME.
