Referring To Bound Column In Multi Select Listbox

So I have a list box that lists organizations. I recently changed the list box type to extended multi select. On the same form, I have a button that opens a new form where the user can input contacts for each organization. When the list box was not multi select, the expression [forms]![media]!

[List30] made the default value of one of the fields in my contact form the bound column from the selection in the list box. However, now that the list box is multi select, the contact input form does not seem to be able to get the value from the bound column in the list box. When multi select is turned on, is the bound column stored differently.

To even get the contact input button to work, I had to change the code from:

Private Sub Command40_Click()
On Error GoTo Err_Command40_Click
Dim stDocName As String
Dim stLinkCriteria As String
stDocName = "Contactsqry"
stLinkCriteria = "[Organization ID]=" & Me.List30

[Code] .....
