Hi,
Is A10 to D17 the named range you call Payer_Verify ?
If not, then the formula given, =IF($I$12=TRUE,INDEX(Payer_Verify,ROWS($A$1:$A1),COLUMNS($A$1:A$1)),"")
will reveal the contents of Payer_Verify if I12 is TRUE.
So.... If you copy the formula into the cell range (say) AA10:AD17 then your named range is revealed there.
If your wanting to hide Payer_Verify itself, as far as I know, you can't, unless your able to hide all the rows and columns it
uses completely.
You can hide text by setting it to the same colour as the background, which might be OK if you also protected the cells
to stop them from being over-written unintentionally.
