set variable to null

[HansBades]

I have a listbox with a delete button next to it. When someone clicks on an item in the listbox and presses the delete button, it removes the item from the list. In my code associated with the delete button, I name the selected item from the list box as the variable itemtodelete. At the end of the routine I am trying to set the variable to null. I have tried both 1) itemtodelete = "" and 2) itemtodelete = null. But it doesn't work. The variable itemtodelete retains the value that was last clicked on in the listbox even though it is no longer there. How can I reset the variable? Thanks.

Just curious, could you requery the form or a specific control on the form?
Perhaps show readers the vba code involved.
