I have createad 2 custom lists, one attaches an ID number to each new item, the other picks up this ID number and allows the user to select the ID number they want. what I want to do is create logic in a workflow that will 'grey out' items in the first list once they have been selected, via their ID number, in the second list.
I have done this in SharePoint 2003 but can't seem to work out 2010.
Any help, greatly appreciated.
