Hello, Everyone!

I am trying to convert text dates to real dates. I need to find all yellow
cells in range B4:B100, strip off the offending text (i.e. Sat. or Thurs),
and use DateValue to turn the rest (which looks like 1/05/2007, but sometimes
1/05/07) into a proper, numerical date in the ddd mm/dd/yy format, arial,
bold, 10pt, and centered in place.

I've spent days trying to write this macro. I've had excellent help from
people on here, but whenever I need to make any slight modification, a
trainwreck ensues. Please see the code below.

Sub switchDate()
Dim MyDate As String
For Each cell In ActiveSheet.Range("B4:B100")
If cell.Interior.ColorIndext < xlNone Then
cell.Value = MyDate.Value
MyDate = Trim(MyDate)
If InStr(MyDate, " ") 0 Then
MyDate = Mid(MyDate, InStr(MyDate, " ") + 1)
End If
MyDate = DateValue(MyDate)
End If
Next
End Sub

This doesn't even begin to work and I can't begin to guess why. Could
somebody out there please make the tweaks and tell me what I did wrong, that
I might not do it hence?

I thank you greatly, and have a terrific day.

Arlen
