Greeting fellow members. I'm in need of a helping hand when it comes to Conditional Formatting combined with Data Validation.

I have a column with drop list Data Validation based on an array of cells. I'm looking for a way of conditional formatting for that column so that it applies if the cell does not contain a valid input. Basically I want to replace the little data validation "wrong input triangle" with conditional.

In other words, i have a sheet specified for the data validation, called "DataValidation", and I want the conditional formatting on another sheet to apply if the cell does not match it.

This column to be formated

Column A
Input1
Input9
Input3
Input7
Input5

if it doesn't contain any of these entries (this column is on another sheet)

Column A
Input1
Input2
Input3
Input4
Input5


There is over 70 entries in the data validation array.

Hope I explained it well enough. Is this doable?

Thanks up front.
