Frost Nova Will Not be Removed

[Skithiryx]

Please help me if you can. I have created a Frost Nova ability that doesn't use mana; it uses "Snowball" charges on a "Snowball" inventory item instead. My trick was supposed to remove Frost Nova if there were no more Snowball charges left, and to replace Frost Nova within the next 8 seconds. But problem is, the trigger is not removing Frost Nova at all.

• Events
• -A Unit starts the effect of an ability.
• Conditions
• -Ability being cast Equal to Frost Nova.
• Actions
• -Set Snowman equal to Triggering Unit.
• -Set Lvl_FrostNova Equal to Level of Frost Nova for Snowman.
• -If, then, else multiple fuctions:
  • Conditions
  • - Item - ((Charges remaining in (Snowball carried by (Snowman) Equal to (1))
  • Actions
  • - Item - Set charges remaining in ((Snowball carried by (Snowman) to (Charges remaining of item type (Snowball) carried by (Snowman) - (1)).
  • - Remove Frost Nova from Snowman.
  • -Wait 8 seconds.
  • -Item - Set charges remaining in ((Snowball carried by (Snowman) to (Charges remaining of item type (Snowball) carried by (Snowman) + (1)).
  • -Add Frost Nova to Snowman.
  • -Set level of Frost Nova for Snowman to Lvl_FrostNova.

For some reason Frost Nova is NOT being removed and I don't know why. How can I get the trigger to remove Frost Nova?

P.S.
I typed in that trigger from memory because I don't have WC3 at the library =/. I hope that was clear enough, but if it wasn't then I will reword it.

K Thx I'll try that out. Do these Custom Scripts work better than setting variables?

The custom scripts are setting variables

The make sure the thing works for multiple units.
