Creating an extra filter

Hi,

I have the Jet Express version and am trying to create a report to calculate how much we have spent for each project.

I am using these filters

Job No.
Job Task No
Job Task Description
No.
Resource name
Description
Total Cost (LCY) - total cost to date

How can I add another column to the same table to show how much was spent for this month alone. I would like for this to be shown next to how much was spent to date (Total Cost, LCY).

Thanks in advance
