On my form, I have "Set Filter" button that has the following code:

with thisform
.oQuery.show()
lcFilter=.oQuery.cFilter
set filter to &lcFilter
.refresh()
endwith

The DE for this form has a table that has a filter always set based on the site the user choose when opening the application. Ex. Inventory.SiteID==gnSiteID.

How can I append the current filter to the filer statement returned form oQuery?

Thanks
