Modify Existing SSRS Report for CRM

I have a custom SSRS report for CRM and I need to replace a field on the report.  The consultant who developed the report is no longer available to help.  Below is the query from the Dataset, I need to replace the field called "new_stateequalizedvalue" with a field called "new_marketvalue".

Any suggestions for how to modify the query to include my new field?
