Colin,

It might be code inside the cbo Requery() that's causing the problem.

>I have a combobox in a grid called cboBuil. In the AfterRowColChange of the grid I have the following code:
>
>This.Column10.cboBuil.Requery
>
>This causes the error PARENT is not an object. If I click on Help when the error comes up it tells me this:
>
>This name was previously defined as something other than an object.
>
>· You have another occurrence of name.
>
>Check your code for duplicate instances of name.
>
>This is no other occurrence of cboBuil. Any ideas?
