Here are 3 suggestions, in reverse order of practicality:
(1) Create a macro that loops through your range and flags you if it returns a False ID, such as (note, not correct syntax, just a concept overview, and not worthy of first choice):
If ActiveCell.HasFormula Then
MsgBox ("Formula")
Else
Offset(1, 0)
Next
(2) Highlight your range of interest and click on Edit > GoTo > Special > select "Formulas", and hit OK. THis will select all the cells in your range with formulas, and you can see that cells not selected are possible culprits.
(3) Most effective, lock your formula cells and password protect the worksheet, so you don't have to worry about this in the first place.

Thanks Tom,
I checked out the Edit, Go To , Special menu and the feature I want is Column differences. I often have to check someone else's spreadsheets and can use this feature to make sure he/she has copied a formula down correctly and not made a change to one of the cells half way down the column.
