I am trying to use a dictionary to replace a value if the field imported is blank.  According to this document, it should be possible (look for #19 - https://omaticsoftware.freshdesk.com/support/solutions/articles/28000006124-what-are-some-commonly-used-regular-expressions-).  However, testing it has proved fruitless.  Any ideas?    

That's a pretty common dictionary. Can you post a screen shot of yours so we can figure out the error?

Sure! I am not receiving an error - it's returning no value at all.  Here is an image of the dictionary:

Your dictionary is looking for the word 'Employee' in the incoming data, and changing it to a blank field. My guess is that you want it the other way around

Yes, haha, that's it.  Sorry, still new to ths!  Thanks for your help!
