Bill,

This is strange!

>I looked at the vp_dDate (which was set up as an object by MM) and the .value property of vp_dDate contains the date I need.

an object?! it shouldnt be an object... it should be a flat local variable with not .value on it.

>As soon as I stepped into the above instruction the dialog box popped up. ???

well ok, if vp_dDate is an object and not a local variable like it's suppose to be, the dialog is popping up because a variable with the same name as the view parameter doesnt exist.

>Its very strange. There is no other reference to vp_ddate on the form or the bizobj except for in the postinit() of the bizobj in the vcx.

Did you set a break point on postinit() to see what the value of This.ddate is before the addviewparameter call is made?

>Does any other property on the form interface with the requery?

Not that I know of. But your problem is NOT really in the requery, it's in defining that vp_ddate in the postinit().
