Hi all:
I have a parametrized view named VIWINV. This view takes a variable (varCode) to filter records (CodeNo=varCode). I have the variable established in the Query/ViewParameters Dialog box, and set in the view designer as ?varCode. I have a form with a grid based on this view. I want the parameter passed by means of selecting a code number from a Combo box. I have the following code in the Interactive Change event of the CBox:

public varCode as character
store this.value to varCode
requery(viwinv)
thisform.refresh
return

but the grid doesn't change to show the . What am I missing?
TIA
