You can do this without VBA

Enter this as data validation formula on E3

=LEN(E2)>0

Also uncheck choose  'ignore blank' and enter error message as I entered.

This wouldnt let any entries on E3 as long as E2 is blank (or length of E2 value is zero)

I have a data validation list in cell E2. &nbsp;I want to prevent data entry in cell E3 if a selection has not been made in E2. &nbsp; Thus display an error message an lock E3<br />
<br />
If a selection is made in E2 than I want to let a data value be entered in cell E3. &nbsp;Thus no message and unlock E3.<br />

I need these actions to occur when focus is on cell E3.
