Hi Rixon.

How about adding a custom property to your second combo called cFilter. Initialize it to some value and set up the RowSource as

sele prefix,imprint2,publisher from publishe into cursor cpublisher1 having publishe.prefix=(this.cFilter)

Then, in the When Method of the combo, you can set

this.cFilter = this.parent.combo1.value

and then just

this.Requery()
