in your dialog you set
set %opl 1
set %hol 2
set %vol 3
set %evl 4
set %offl 5

but in the script you have
if (%aol == 1)
elseif (%ool == 2)
elseif (%hol == 3)
elseif (%evl == 4)
elseif (%offl == 5)

i dont see where these vars get set
if (%aol == 1)
elseif (%ool == 2)
elseif (%hol == 3)

i also dont see where these variables get used
set %opl 1
set %vol 3
