Custom Spell Import

Hey can someone import the Water Explosion spell (made by Dark_Dragon) into my map and send it to me because i am either stupid or something else is wrong, because i did everything the script asks even the custom raw codes, and when I save the map i get tons of PJass errors + i cant open the map in Frozen Throne. Please help me, this spell is very important for my map, of course both Dark_Dragon and the person who helps me will get full credit.
