Hi there, I am using ASP Javascript (not VB) and i want one field of recordset2 to be a repeat region , but i want it controlled by field "city" from recordset1 to be equal to field "cityad" from recordset2 to display field "ads" from recordset2 as a repeat region.

I am at a loss I cant make this work. any help would appreciated.
