Calculating saving throw in a DG script was created by Nero

Trying to have a mob apply a strength debuff but first I want it to calculate the saving throw and level of a player..the greater the level/saving throw, the less chance it has of actually applying the debuff. For some reason it just keeps failing to apply the debuff and giving me my fail message. Not sure how to fix this.

Code:

set actor %self.fighting%
if (%already_fighting%)
  wait 6 secs
  unset already_fighting
else
  switch %random.3%
    case 1
if  (%target.affect(CHARM)% || %target.is_pc%)
     eval ss %target.saving_spell%
      if %random.150% > %ss%
           %send% %actor% You feel the undead tree draw the strength out of your body. %actor.str% %randomizer% %target.saving_spell%
               else
               end
           dg_affect %target% STR -1 on 5
      else
           %send% %actor% You resist the undead tree's attempt to draw the strength from your body. %actor.str% %randomizer% %target.saving_spell%
               else
               end
               break
    default
               break
  done
    set already_fighting 1
    global already_fighting
end

What exactly is the error message?

As for the script, I'll have to think it over some more, but one thing I've noticed is that you unset the global variable. I don't recall there's a better way to do that? I'll look into it and let you know if I think of anything.

Addendum:

Shouldn't you use %actor.varexists(variable)% on your targeted victim when using globals?

I've been playing around with it and have it somewhat solved
My only problem is trying to figure out how to make this where the affect considers the players level/saving throw to determine if the affect lands or they resist.
As of right now it always lands and removes the target's strength.

Code:

set actor %self.fighting%
if  (%actor.affect(CHARM)% || %actor.is_pc%)
  switch %random.5%
  case 1
    wait 7s
    eval ss %actor.saving_spell%
    if (%random.100%-(%ss%)>=0)
      %send% %actor% You feel the undead tree draw the strength out of your body.
      dg_affect %actor% STR -1 5
    else
      %send% %actor% You resist the undead tree's attempt to draw the strength from your body.
    end
    break
  default
    break
end

Your switch statement doesn't appear to be closed. This might not be the issue, but it certainly can't be good.

Code:

    end
    break
  default
    break
  *done <-- needed here 
end

Thanks, I corrected that. I am still struggling to figure out how to balance this. As the player's level goes up, the saving spell goes down. So trying to figure out a logical way to code this that allows a higher level player more chance to resist the mobs affect.

What's the point of your switch statement? Are you hoping to have other effects besides strength reduction?

Couldn't you have a series of if/elseif statements for different calculations of your random value versus saving throw?

ie

Code:

set drain_str %random.100%
if (%drain_str% - %ss% <= 100) && (%drain_str% - %ss% > 90)
   * do something
elseif (%drain_str% - %ss% <= 90) && (%drain_str% - %ss% > 80)
   * do something else
elseif (%drain_str% - %ss% <= 80) && (%drain_str% - %ss% > 70)
    *do another thing
...
elseif (%drain_strain% - %ss% <= 10) && (%drain_str% - %ss% >= 0)
     *do final thing
else
     *message character of failed attack
end.
