Exit button not closing the Run Time Window

I'm updating some older courses for a NEW LMS, and I'm not a coding expert

1. The LMS runs an adl.nav.request of “exit” which currently takes the SCO away without closing the RTE, presenting the user with the interstitial page
2. I'd like to add the following adl.nav.request call when the close button is clicked...

   1. If incomplete status – adl.nav.request = “suspendAll”
   2. If completed status – adl.nav.request = “suspendAll” or “exitAll”

When I try to put an action on adl.nav.request, it rejects the variable because it cannot have a period " . " in it.
