I'm sure some of you wonderful calculation guru's will be able to help me easily with this! Yes I am trying flatter you all

Here's the situation. We have a customer who pays up front by a PO number, 10 call outs to repair printers. Now, in order to see how many they have left, I would like next to the PO number field to add a field that counts all the records with the same value.

Is this possible?

You haven't provided enough info for me to offer an answer. What tables do you have (beside PO), and what do you mean by "how many they have left?"

There are many ways to "count records with the same value in a field." One way is to create a calc that equals 1 if the field has the desired value, ie flag_green =1 if field color = "green". Then either use a summary field to total the flag field or if related sum (relationship::flag_green) or selfjoin. Other people prefer to use Count ( ) and FilterValues ( ).
