Hi all,

I've set up a Named Range that refers to an array of constants, e.g. MyRange ={1,2,3,4,5}. This appears to be fine since I can output the named range to a range of cells in a row (e.g. A1:E1) and see 1,2,3,4,5 (one value in each column).

I'd like to use MyRange as the source for a Data Validation list in a cell.

Normally data validation list sources must be vertical, so I've set MyRange =TRANSPOSE({1,2,3,4,5}). This appears to be fine since I can output the named range to a range of cells in a column (e.g. A1:A5) and see 1,2,3,4,5 (one value in each row).

When I set MyRange as the source for data validation however, it resolves to an error.

Anyone have an idea why this setup doesn't work?
