It sounds to me like you are using a form that someone there at your company
set up to search a list of PO's on your local network, increment it and then
use that as the next one...........be that the case, very probably the link
has been broken by your MIS moving the directory and or remaning it, or
changing rights etc etc.......it happens to me all the time, no notice,
nothing, they just move things around and Excel has no way of knowing where
it went.  Talk with your MIS guy and see if he can locate the list for
you...........if it was working before, it probably will again once you
locate the list......but you may have to modify your form if MIS won't put
it back where it was.........or create a new one.........lotsa "if's" here,
I know, but maybe this will give you a lead...........
