Mass edit multiple workbooks of the same format - vba

Question

I'm very new to VBA (as of this morning), so excuse my ignorance. I have a few hundred Excel workbooks, all formatted exactly the same way (just with different text). I'm trying to both format and delete a few sheets within the workbooks (the same for alL).
I recorded a macro that works fine when applied individually, but I'm getting a runtime error when I try to run this as a means of mass format:
Sub LoopFiles()
Dim MyFileName, MyPath As String
Dim MyBook As Workbook
MyPath = "I:\Academic Networks\All scorecard copies, 6.18.2015"
MyFileName = Dir(MyPath & "*.xlsm")
Do Until MyFileName = ""
Workbooks.Open MyPath & MyFileName
Set MyBook = ActiveWorkbook
Application.Run "Workbook1.xlsm!ScorecardMacro"
MyBook.Save
MyBook.Close
MyFileName = Dir
Loop
End Sub
I keep getting a runtime error (9) - Subscript out of range. Any thoughts?
Here's the formatting/deleting I'm trying to apply to all my workbooks (which works fine when applied to one workbook at a time:
Sub ScorecardMacro()

' Scorecard Macro

Sheets("Scorecard").Select

Answer 1

The error shows you are trying to access something that doesn't exist.
Since you are deleting something, its better to do all you updates first, then do all the deletes in the end.
If you do some deletes in between and then update, there might be some values/sheets missing

Answer 2

You are referring to a named range called "filename":
"=MID(CELL(""filename""),SEARCH(""["",CELL(""filename""))+1,SEARCH(""]"",CELL(""filename""))-SEARCH(""["",CELL(""filename""))-1)"
I suspect that name is not defined in the other workbooks.
