Here is some code that I'm working on. It's choking on the second loop
statement. I'm getting the Run-time error '1004': Application-defined or
object-defined error. I get this error message all the time and it's driving
me nuts. After some fiddling I'm able to work around it but I can't get past
it this time. Here's the code:

Dim DateValidation As Range
Dim SingleDate As Range
Dim ManningDate As Range
Dim BlankCounter As Integer

Set DateValidation = Application.InputBox(Prompt:="Please select the week(s)
to validate on the Yearly Manning sheet.", _
Title:="Select week(s) to validate", Default:=Selection.Address, Type:=8)
On Error GoTo 0

If DateValidation Is Nothing Then Exit Sub

For Each SingleDate In DateValidation
If Not IsDate(SingleDate) Then
MsgBox "Please select only the week ending dates that you wish
to validate", vbInformation, "Oops, wrong spot"
Exit Sub
End If
Next SingleDate

For Each SingleDate In Sheets("Yearly Manning").Range(DateValidation.Address)

BlankCounter = 0

For Each ManningDate In Sheets("Yearly
Manning").Range(SingleDate.EntireColumn)

If ManningDate.Value = "" Then
BlankCounter = BlankCounter + 1
Else
BlankCounter = 0
End If

If BlankCounter 15 Then
Exit For
Else
'''Do more stuff here
End If

Next ManningDate

Next SingleDate

The error message is coming up on the second loop statement: For Each
ManningDate In Sheets("Yearly Manning").Range(SingleDate.EntireColumn)

What is wrong with using the entire column as my range? As you can I have a
BlankCounter to get out of the loop once I go through enough blank rows.
