Control Display of Drop Down List in Validation

[dschlamp17]

I am currently working on a order form that requires an "X" to be placed
in order to make a selection. The problem being is that some options
have a drop down list composed of a named datarange or a straight text
string. Which in turn completes the option price based on what is
selected.

I want to be able to not show the drop down contents until the "X" is
placed
in the proper field by adding a formula to the cells validation.

Thanks in advance.

You can create another named range, NA, with one cell that contains "N/A"
Then, in the data validation dialog box, choose Allow: List
In the Source box, type a formula that refers to the cell that should
contain the "X":
=IF(E8="X",MyList,NA)
Remove the check mark from "Ignore Blank"
Click OK
