else ($2 !ison #) && ($2 !== help) {
[ ... ]
Else ($3 !ison #) {

these two lines are incorrect, and will result in a '($2 Unknown command' and '($3 Unknown command' if those else cases are reached.

'else' doesn't take a condition, and you shouldn't need to include one if you use proper if / elseif branching logic above it. for example:

  if ($2 ison #) { }
  if ($2 == help) { }
  else { }

the 'else' here applies only to the second if ($2 == help). this is the logic you're aiming for:

if ($2 ison #) { }
else {
  if ($2 == help) { }
  else { }
}

which is equivalent to:

if ($2 ison #) { }
elseif ($2 == help) { }
else { }

take a look at /help /if because these are basic fundamentals
