Excel add-in filter function

Hi,

I'm new to Business bydesign so will probably be on a here a lot... My issue at the moment is that I've installed the Excel add-in and have set up a financial statement report and I'm trying to set up a filter where it only pulls in GL accounts beginning with a 6 but can't seem to do this.

I'd be very grateful if someone could point me in the right direction and apologies if I've posted this to the wrong section etc. I'm still learning!

Thanks

Paul
