The fact that 1 cell is manually entered and the other is the result of a calc will make no difference to excel, as excel sees what teh cell displays, not what it contains (formulas etc)
Not sure how you were using MATCH(), but this will return a cell position, and you dont need the "" in IF(Cell1=Cell2,"1","0"), just use IF(Cell1=Cell2,1,0). Using "" turns the 1 and 2 into text, so you might just as well have said IF(Cell1=Cell2,"YES","NO"). Likewise, if you are dealing with text in a cell, changing the format to text will also make no difference, excel already see's it as text
If your formulas are not seeing the 2 cells as containing teh same data when it looks like they do, check for leading/training/extra spaces.
Perhaps upload a sample workbook, and I can take a look and see whats going on for you?
