Perhaps the Lead provider name comes in multiple variations and you'd like it to be set to one spelling standard.  For example, Autotraders, sends out leads under:, AutoBytel, Autobytel/XYZ, etc. and you'd like it to just be listed in one standard way of just "Autobytel". Here's how you do it:

Select: IF, <name part="full">xyz</name> , Change , Provider, <name part="full">Autobytel</name>. 

Then click "Save Rules", you should receive a success message. You can either continue with more rules, or scroll down and click "Next" to get you to the Intake Sheet Tally page for Publishing.
