Alex,

I finally got it to work. The wrapper report acts as the normal report would, by gethering properties from the parameters form and loads the appropriate data environment. In DataEnvironment.Init(), I have to following code:

IF lCancelReport
	RETURN .F.
ENDIF

LOCAL ;
	lcTo,;
	lcReportForm,;
	lcTextFile,;
	lcReportStr
	
*--------------------------------------------------------
*--- Instantiate the Data Environment
*--- This will load all cursors needed for the report.
*--------------------------------------------------------
This.AddProperty('oDataEnvironment')
*--------------------------------------------------------
*--- tcDataEnvironment is returned from the parameter form
*--------------------------------------------------------
This.oDataEnvironment = CREATEOBJECT(tcDataEnvironment)

*--------------------------------------------------------
*--- This section gets whether the report is printed to
*--- PRINTER, FILE, OR PREVIEW
*--------------------------------------------------------
lcTo = PROGRAM(PROGRAM(-1) - 1)
lcTo = UPPER(SUBST(lcTo,RAT(".",lcTo) + 1))
lcTo = STRTRAN(lcTo,"SENDTOTEXT","")

lcReportForm = "VaccineAdministered" + tcClinicSummary
lcTextFile   = lcReportForm + ".txt"

lcReportStr  = "REPORT FORM " + lcReportForm + " TO " + IIF(lcTo = "FILE","FILE","PRINTER") + " " + IIF(lcTo = "FILE",lcTextFile + " ASCII","PROMPT " + IIF(lcTo = "PREVIEW","PREVIEW","NOCONSOLE"))

&lcReportStr.

RETURN .F.

Thanks for your help.

I am trying to create a blank report, with no dataenvironment, to call the correct report form based on my input, but am running into problems.
