I guess this is a piece of cake for you people but I've been reading the FMP 8 Help in and out.

I need the auto-fill of a calculation of quantity * price.

The quantity is defined in a scroll down menu and the price is written in a field next to it. I've tried many times to get it right and though this formula would work:

Tshirtquantity * Tshirtprice

But nothing happens. What do I do wrong?

Many thanks in advance for your time.

Uncheck the "Do not replace..."

Hmm. Cannot find that box, where exactly is it?

Sorry and many thanks for your reply.

I am guessing that you are using a number field with a calculated value.

In the options for TshirtTotal, the "Do not replace..." checkbox is on the Auto_Entered tab, below the Calculated value option.

ah, now. Thank you very much for your time.
