Can pass subform Recordsource to a Re****t

I have a form where two listboxes filter data so a subform quickly displays

filtered records. Coding allows for multiselect, and a SQL string is 
generated and applied to the subform recordsource:

       Forms!ReviewSamplesResult!Details.Form.RecordSource = strSQL

Since the user needs to be able to print this subform data, I created an 
OpenRe****t command button.

How can I pass the SQL that was built to generate the data for the re****t?
I tried things like
-----------
Dim strLinkCriteria As String

stDocName = "rptReviewSamplesResult"
strLinkCriteria = Forms!ReviewSamplesResult!Details.Form.RecordSource
DoCmd.OpenRe****t stDocName, acPreview
-----------

but did not fly. I am not very familiar with using OpenArgs and was 
wondering if it could be a way to pass the data. also, don't you need to 
provide the RecordSource BEFORE the Re****t opens?

Thanks for help.
