Datatype Mismatch Error, Can't Figure Out

Hi,
When I click this buton I get an error on one of the following lines.. I can't figure out why and how to fix it.
the error I get is
run-time error '3464':
Data type mismatch in criteria expression.
I made the part where the error occurs in bold and italics

'submit for approval
Private Sub Command22_Click()
Dim rs As Object
Dim rs2 As Recordset
Dim db As Database
Dim name As String
Dim x As Integer 'will be used as flag for do while loop
Dim cnt As Integer 'this will contain the number of records in the recordset

'MsgBox (Me.projno)
Set db = CurrentDb

Answer = MsgBox("Are you sure you want to submit this timesheet?", vbYesNo)
'if cancelled
If Answer = vbNo Then
Else
x = 0 'initialize flag
Set rs = Me.Recordset.Clone

rs.MoveLast
cnt = rs.RecordCount
rs.MoveFirst

Do While x < cnt
If rs!statusPM = "pending" Then
MsgBox "This timesheet has already been submitted. You can't submit this again."
x = cnt
End If
If rs!statusPM = "approved" Then
MsgBox "This timesheet has already been approved by your supervisor. You can't submit this again."
x = cnt
Else
MsgBox (rs!projno)
Set rs2 = db.OpenRecordset("SELECT projmanager FROM Projects WHERE projno =" & rs!projno)
Do While Not rs2.EOF
name = rs2!projmanager
MsgBox (name)
rs2.MoveNext
Loop
rs.Edit
rs!statusPM = "pending"
rs!status = "pending"
rs.Update
x = x + 1
'MsgBox (rs!projno)
rs.MoveNext
End If
Loop
'clear variables
Set db = Nothing
Set rs2 = Nothing
End If
End Sub

Thanks in advance,
