loading data into form

Question

Hi,

I have a form with a listbox in it.  I want to give the user an option to select an item and edit it.  I want an edit window to open up with all the information there is on the item to be loaded.  In the form with the listview in it, I set the variable for the item, but when the window opens the variable turns to null.  How can I get around this problem???
