Help with Fire

[Tiger]

So my current delema is setting Mobs on fire. The 2 key values are "On Fire" and "HP" Here are the list of events:
When Group.enemy colides with fireball: Set "Fire" to 50; Subtract 5 from HP; Create object "Fire" at 0,0 from Group.Enemy
When value "On Fire" of Group.enemy >50; every 0.10 seconds: Subtract 1 from value "Fire"; Subtract 1 from Value "HP"
When value "On Fire" of group.enemy >0: set "Fire" position at 0,0 group.enemy
When Value "On Fire" of group.enemy =<0: Destroy Object "Fire"

Ok, would you give more information on what is needed?

Thanks,
