Application-Defined or Object Defined Error

All,

I am getting an Application-defined or object defined error in the last line of my code below.

Sub Compare()

    'Calls workOnSheet.  This opens up CostPoint file and formats for use.
    Call workOnSheet
    
    If StopFlag Then
       Exit Sub
    End If
    
    '===========================================================================================================
    'Get hours off of Timesheet Daily Detail Inquiry for the first Person.
   Set gplainId = ActiveSheet.Cells(3, 2) 'Find the employee Id of first person
   Set glastName = ActiveSheet.Cells(3, 3) 'Find the employee id of the first person
   Set gboldId = ActiveSheet.Cells(4, 2) 'Find the employee Id of the first person as bold
      
   With Workbooks(DEFName).Sheets("Page1_2").Range("A:A")
        Set ge = .Find(gplainId, LookIn:=xlValues)
        If IsEmpty(Worksheets("PATH").Cells(2, 2)) Then
            MsgBox "Requested Project Does Not Exist", vbExclamation, "No Such Project Code"
            Exit Sub
            Else:
            On Error Resume Next
            gbeginRow = Str(ge.Row)
            If Err.Number <> 0 Then
                MsgBox "Requested Project Does Not Exist", vbExclamation, "No Such Project Code"
                Exit Sub
            End If
            On Error GoTo 0
        End If
   End With
   
   Debug.Print gbeginRow
    
   With Workbooks(DEFName).Sheets("Page1_2").Range("B:B")
        Set gcell1 = Cells(gbeginRow, 2)
        Set gd = .Find(glastName, After:=gcell1, LookIn:=xlValues)
        gstartRow = Int(gd.Row)
   End With
    
   Debug.Print gstartRow
   With Workbooks(DEFName).Sheets("Page1_2").Range("A:A")
        Set gcell2 = Cells(gstartRow, 1)
        Set gc = .Find(gboldId, After:=gcell2, LookIn:=xlValues)
        gendRow = Int(gc.Row)
    End With
    Debug.Print gendRow
 
     '****** GOT TO HERE**********  Want to get the hours somehow and put in checker.
 ' You need to get a range for the employee id or name along with the charge code.  You don't have this at the moment.
    gsRng1 = Range(Cells(gstartRow, 2), Cells(gendRow, 2)).Address(False, False) ' Get the name with this one.
    gsRng2 = Range(Cells(gstartRow, 18), Cells(gendRow, 18)).Address(False, False) ' Get the hours with this one.
    gsRng3 = Range(Cells(gstartRow, 13), Cells(gendRow, 13)).Address(False, False) ' Get the charge codes with this one
    gsRef = "[" & DEFName & "]Page1_2"
    
     
     For gtheRow = 3 To 20
        ggetHours = "=SUMIF(" & gsRef & gsRng3 & ", """ & Cells(gtheRow, 5).Value & """, " & gsRef & gsRng2 & ")"
        Debug.Print ggetHours
        'Range("E5") = "GOT HERE"
        Cells(gtheRow, "F").Formula = ggetHours

End Sub

The code 'Cells(gtheRow, "F").Formula = ggetHours is throwing the error. Please help if you know what I am doing wrong. I have basically the same type of code in another workbook with a slight twist on it, and it does not throw an error out at me.

Thank you -- SEOT

I did miss the explanation point! I should have known that much. I was not aware of the single quotes though. How did you know about those? What is the rule on those things? I am very greatly apprecaitive of you for fixing my code. It works now!! Thank you!!! -- SEOT
