I have a form which I use to invoice clients.  This is actually 1 form with 2
subforms
Client - Invoice# - Charge Detail

I Have a combo box to choose the client on the client form.

I have a combo box to choose the invoice# on the invoice.  I am trying to
filter the invoice's to only show the invoices for the current client shown.  

I have a query for the combo box where the client field is filtered to the
current client.  This seems to work for filtering the invoices to only that
client the first time I use it, but if I change the client the invoice
remains filtering to the first client that was chosen.

I tried to do a save command on the client field but that hasn't worked
