code in Case Select to open union query based report

[starrcruise]

I have searched everywhere for help on this. I hope you're my saviors again. I have a switchboard form that has a combo control with lists of reports to be chosen. In the VBA of control, I have a case select. (pasted below). I currently have the code below opening a report (built on a union query) when the "Division Affected" field equals the input box. It works perfectly.

Case 5 'opens Compliance open items report by Division
If Me.cboReportTask = 5 Then
strDiv = InputBox("Please enter Division Name:" _
& vbCrLf & "Retail, Correspondent, Wholesale," _
& vbCrLf & "RTL/WHSL, RTL/CORR, WHSL/CORR")
strCondition = "[Division Affected]='" & strDiv & "'"
DoCmd.OpenReport "rptComplianceOpenItems", acViewReport, , strCondition
Me.cboReportTask = ""
End If

Now I need it to open as follows:
If "Retail" entered in input box, then if "Division Affected" = "Retail", or "RTL/Whsl", or "Rtl/Corr", it will be pulled.

I tried entering an If statement
If strDiv = "Retail" Then _
StrCondition = [Division Affected]=???????
However, I do not know how to set up the StrCondition statement. several attempts resulted in mismatch 13 error, another was 2465 '|' field cannot be found. I am obviously not referring to the field properly in my string, or my syntax is wrong. I'm lost. Thank you for your help in advance.
