Error code when attempting to View Report

[Robert2150]

I have a database that has been running well for over a year.
I am now getting the following error when clicking button to View Report; Microsoft Visual Basic, Run-time error '3464', Data type mismatch in criteria expression. The following is the code for viewing report when button is clicked.

Private Sub VIEW_SQ_FT_LN_FT_EA_ITEMS_REPORT_Click()
Me.Visible = False
strWhere = "[Property Number] = " & Me.[Property Number]
DoCmd.OpenReport "SQ FT/LN FT ITEMS REPORT REV ADMIN", acViewPreview, , strWhere
DoCmd.ShowToolbar "Ribbon", acToolbarNo



End Sub

Any suggestions? Thank you for your help in advance.

Does the report open without error if you remove the strWhere filter.
If so, then the issue would have to be that the datatype for Property Number field has been changed e.g. to text

I can't quite believe that you have a report with that name. It's too long, contains spaces and a forward slash. Why?
Similarly for your procedure name. Slightly better due to underscores but overcomplex

What about if the referenced control is Null?
Agree about the name. Sometimes too much explanatory info ends up in names when the object properties could contain notes instead. Maybe rptSqLnFtPerItem...

Hi micron

If the referenced control is null, a different error will occur. Probably syntax error 3075 but easily solved with use of Nz or error handling
