Multiple Dates for funnel-ish!

[AlAlawiAlawi]

Hello Everyone;

I am frustrated with this and waiting for super geek to hit me on the head.

The screen shot says it all, first part is te sample data,

Then usually what most look at are if the Sales Figures match the month so predominantly invoice date is the filter

The last bis is what the data should look like.

How would super geek reach that required result !
