Counting a Field thats NOT in the report itself

Hello,

I need to count the {JobRecord.JobNumber} that was "planned" for our techs to complete.

However, it is not on the report itself. The field it should be coming from is {JobRecord.ProjectedIssueDate}.

My report is grouped as follows...

Group #1 Name: JobHours.StartDate

Group #2 Name: JobRecord.ContractorName

Group #3 Name: JobType.Description

So if a Job Type (Preventative Maintenance) is planned for 8 PMs to be done on 8/25 but the men only complete 7 on 8/25. Then I need the summary to count 8, not the 7 that they completed on the start date.

Please help and thank you. Let me know if you need anymore information.
