Find dates and do summary of invoice totals

[Madwolfie]

I have been following posts on finding within date ranges, but they don't seem to help my problem and I am finding it very taxing!

I have a report with a list of invoices and a summary of their total. What I would like is: a button to run a script to produce a summary total of the invoices for a specified date range (this would be either a certain month or a full year between specified dates).

I would prefer two user entry fields to be able to enter two dates for a date range).

Hope you can help

Cheers :confused
