I need to write a formula where if a range of cells all are marked with an x then the cell autopopulates "x", if only some are marked, then "In Review", and if nothing then nothing.

I currently have
=IF(AND(c8:c15="x"),"x","Review"))
With ctrl shift delete

How can I have this cell be blank if none of the cells in the cell range are marked?

Thanks for any help sorting this out!
