    stDocName = "NewGrievanceReport"
    DoCmd.OpenReport "NewGrievanceReport", acPreview, , "[GrievancesTbl_new].[ID]=" & Me.Involved_subform.Form.IDLink
Exit_Print_Preview_Click:
    Exit Sub

Err_Print_Preview_Click:
    MsgBox Err.Description
    Resume Exit_Print_Preview_Click
   
End Sub

Answer : sub report with null fields

ssblue:
  I'm going to bet that the query for this report's subreport uses INNER joins or no joins at all.
  This means that if there is no match between the records of the main report and the sub report that you WILL NOT GET a return of records.  

Change the query of the subreport to include the main table from the main report.  Use Master/Child linking to have the subreport associate UPWARD to the main report on the key fields.

What you want to happen is that in EVERY report you want a record (even if there are alot of null values) to populate the subreport.  You can do this by having part of the main table act as that record.  Using LEFT JOINS from Main table to sub table you create a condition where the main supplies the key fields for the subreport record, EVEN IF NO RECORD EXISTS IN THE SUB TABLE.

does this make sense to you?
