I have several macros built into this workbook. One of the macros is supposed
to clear all fields in several different ranges. I get the error "cannot
change part of a merged cell" and then when i removed any merged cells from
the ranges i get some kind of global error. i wiil post my macro here, can
anyone tell me what i'm doing wrong?

Workbook :

Option Explicit
'Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
' Call ChkData
' If CancelA = True Then Cancel = True
'End Sub
Private Sub Workbook_Open()
Dim RngName As Variant
For Each RngName In Array("ClearEOSV1", "ClearSEMErrorsV1",
"DEVLogOlivetteV1", "DEVLogOverlandV1", "ClearNMXNSGV1", "ClearNMXSIMV1")
Range(RngName).ClearContents
Next RngName
End Sub
Private Sub Workbook_BeforeClose(Cancel As Boolean)
MsgBox "Double check everything before you save!"
Dim res As Long
res = MsgBox(prompt:="Did you check all of the SEMs?", _
Buttons:=vbYesNo)
Cancel = res = vbNo
res = MsgBox(prompt:="Did you check all of the NC1500s?", _
Buttons:=vbYesNo)
Cancel = res = vbNo
res = MsgBox(prompt:="Have you forgotten to validate your timestamps?", _
Buttons:=vbYesNo)
Cancel = res = vbYes
End Sub
