Are you sure you haven't unchecked "show error alert after invalid data is
enterd"?

I've used the Excel 2003 Data Validation Warning and Stop funcitions in the
past successfully. I have a new spreadsheet that is not providing a pop-up
when the value is not from the list.
The lists are on a separate worksheet within the same workbook.
I am referencing the list by 'naming' the list and using '=namedlist' as the
list source.
The list does appear as a drop-down with the correct values.
However, I can input any other value in the column.
I have tried clearing and re-adding the error alerts.
They still do not work.
Can someone direct me on what might be the cause?
