I know this can be done because I am doing this in another workflow.  <br>
I am taking a Workflow Global Value as the destination.  The entry type is a File Cabinet.  I am literally making the same WHERE clause, just using different field names.  I set up an e-mail trap to report back all of the fields and they all come back correctly, except the field that accesses the other file cabinet and it is blank.<br>
The only difference is that the one that works was created in 7.2 and we just upgraded to 7.7.  I hope that this upgrade is not going to break the feature.
