Excel 2007 :: Search / Replace Multiple Words In Table

I am using excel 2007. I have a worksheet with a list of words I wish to step through this list replacing the selected words in another workbook with nothing (ie deleting them).

I have the following code

Code:
Sub replacewords()
Dim MyWord As String
Dim wbLibrary As Workbook
Dim wbWorking As Workbook
Dim myExcelColumns As Integer
Dim myExcelRows As Integer
Dim MyRow As Integer
Dim MyRange As Range

[code].....

It does not seem to evaluate "myRange";
