InstallAware

I cloned a dialog (save as) and setup 2 radio buttons.

NewClean and OlsExist

I am trying to set the checked radio button at runtime to OlsExist
when I run it (and debug) the first radio button (newClean) is highlighted and when I click
BACK it does not flag the WIZARD variable as back so it does not go back.

This should be simple, I must be missing something is not obvious here.
thanks

================
label: New or Exist
Set Variable OlsExist.checked to TRUE
Set Variable NewClean.checked to FALSE
Set Variable NEWCLEAN to FALSE
Set Variable OlsExist.checked to TRUE
Display Dialog: neworexist, wait for dialog to return (modal)
if Variable WIZARD Equals BACK
GoTo Label: User Registration
else
if Variable WIZARD Equals CANCEL
GoTo Label: Main Install
end
end
