Conditional format a cell with a drop down value with a different text based on another cell date value

[Mr Dean]

how to Conditional format a cell with a drop down list with a different text value depending on another cell which has a date entered.

[TABLE="width: 500"]
<tbody>[TR]
[TD][/TD]
[TD]A[/TD]
[TD]B[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
</tbody>[/TABLE]

If A1:Z1 uses a drop down list containing multiple items ie. review, checked, completed and B1 has a date which is manually entered when completed, can A1 be formatted to then show the word 'closed'?

Conditional formatting doesn't change values in the cells its applied to, only the format of those cells.
