Multiply 2 fields from different tables

### Post

I have two number fields from different tables and I need to multiply them in a calculation to create a field in one of the tables. However when I do, I get no value as in question marks.

I don't know what the problem is or how to get around it, help please :)

Are the two tables related? And if so how?

Can you give us a little more information?

Because this shouldn't be a problem, the only important bit is the relationship between these two tables.
