took the advise
Code:
;the ubound($string) equals 3
;calling string[4] will cause an error.
$string = "a:b:c:d"
$string = split($string,":")
$var = $string[4]
;but, this does not cause an error...
$string = "a:b:c:d"
$var = split($string,":")[4]
changed
Code:
$aPerms=Split($line,':')
$sPerms=$aPerms[1]
to
Code:
$aPerms=Split($line,':')[1]
no errors
