signature code question

[Boofo]

Could someone please tell me how I would combine these two statements into one and still have them do what they would individually?

'signature' => iif($bbuserinfo['signature'] !== '', true)

and

'signature' => iif($bbuserinfo[fieldXX] == 1, false, true),

[Xenon]

'signature' => iif($bbuserinfo['signature'] !== '' AND $bbuserinfo[fieldXX] != 1, true, false)

Ok, with the second variable, that means if the box ISN'T checked, right?

[Xenon]

correct

Thank you, sir.
