If value is met hide/reveal named range

I'm looking for a formula that if the value "True" is met in cell i12 then my named range "Payer_Verify" will reveal. If this value is not met then it will be hidden until it is.

Assuming the named range is a single column, then something like:

=IF($I$12=TRUE,INDEX(Payer_Verify,ROWS($A$1:$A1)),"")

copied down

else if it is multicolumn.

=IF($I$12=TRUE,INDEX(Payer_Verify,ROWS($A$1:$A1),COLUMNS($A$1:A$1)),"")

copied across and down

It doesn't seem to be working. Its a multicolumn named range. The range I'm trying to reveal is A1017 if I12 is True. If its not true it stays hidden until then.

You tried?

=IF($I$12=TRUE,INDEX($A$10:$D$17,ROWS($A$1:$A1),COLUMNS($A$1:A$1)),"")

if still no, then maybe your TRUE is a text string rather than a boolean

=IF($I$12="TRUE",INDEX($A$10:$D$17,ROWS($A$1:$A1),COLUMNS($A$1:A$1)),"")

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.
