Crystal reports unlinked sub report with Parameter generates error on main report

I don't know if what I'm trying to do is even possible.  I'm fairly new at Crystal, and am using Crystal in conjunction with Epicor.

I have a sub report that I want to print on a main report.  The two reports have nothing in common.  The main report is grouped on three fields, and the data appears in the group footer #3.  The records are selected based on an option field's input.


The sub report is grouped on one field, and the data appears in that group footer.  The subreport requests a Job Number parameter, which will return the appropriate material information for that job.  There is a record selection formula that includes the parameter.

I want this to print in the group footer #3 for the main report (like a continuation of the grouped data).  The sub report works perfectly on its own.  The main report works perfectly on its own.  

When I put the sub report in the main report, and test the report, I put in the main report option (a shipper number).  Then the request for the parameter input pops up, and I put in the Job Number, and then I get an error message telling me that there is an error in the record selection formula because the field name is not known.

First, is what I'm trying to do even possible?  
If it is, I'd truly appreciate any direction.  I have been fussing with this off and on for weeks, and I am clearly spinning my wheels.

Thanks in advance!

If you are able to run the report in Crystal Designer but it fails in Epicor the problem is in Epicor. Did you try to run the report with another viewer ?

Also, it is a better practice to define the subreport parameters  on main report level and pass them down to the subreport ( by linking the subreport parameter to the main report parameter)

WHat version of Crystal are you using?

Is it a stand-alone version or is it an Epicor OEM version?

vasto - I am able to run both reports in Epicor, but not once I put the subreport in the report.

How do I link the subreport parameter to the main report parameter?

mlmcc - I have Crystal Reports 2008, and I can use it stand alone, but mostly I access it through Epicor, due to that automatically putting the reports in the desired locations.

To link to a subreport parameter

When you link a subreport you can choose any field from the main report including main report parameters.

After selecting the main report field/parameter 2 new boxes appear.
The left box is the mechanism for passing the value.
By default Crystal creates a parameter and names it ?pm_FieldName
If you have a subreport parameter you need to click the combo box and scroll down to it.  It will be named ?ParameterName.
When you do that the box on the right is no longer available because it assumes you have used the parameter in the subreport as it is needed.

Step
Right click the subreport
Click CHANGE SUBREPORT LINKS
Select the field/parameter from the main report
Use the new left hand dropdown/combobox to select the parameter from the subreports
    Don't use the one Crystal provides
Click OK
