InfoPath Dev

I have a repeating table with 3 columns.   One column is a textbox and the other 2 columns are dropdowns.  I would simply like to tally all possibly combinations within the 3 column types and display them in seperate fields.  Is this possible by using just the form functionality or do I need to add managed code?  BTW I am using Infopath 2003 and must publish to Shareppoint.

Thanks  

Hi!

What do you mean by tally all possible combinations? All of your data is numerical? You can definitely use expression boxes and filtered XPath to get sums, but a lot depends on what you are trying to do. If it is hard to explain, you can always attach your template (under the Options tab) so someone can help out....
