I'm trying to pass a parameter to my query in the criteria field. The parameter is contained on a form in the combobox cboReportSender. cboReportSender contains a list of departments that I run reports for. Also contained in the list is " ALL". When this is selected, I wish the report to display all records. I'm sure that the query is looking for a field literally containing "Like \*"
Am I going at this from a wrong angle?

`IIf([Forms]![frmRunReport]![cboReportSender]=Trim(" ALL"),"Like *",[Forms]![frmRunReport]![cboReportSender])`
