Speel Editing Questing...unit to hero spells

I am making a spell which takes unholy frenzy and makes it a hero spell. everything seems to be working properly, but after testing the spell, it shows up passive on the hero. i am not sure if it is possible to take a unit spell and convert it to a hero spell.
if anyone has any idea why this is happening plz let me know....

Waht you have written looks fine, the part your missing is in the abilitydata.slk you have to find the spell your changin change the hero field to a 1, the field that says unit to hero and the total levels to 3 with a required level of 1... then your going to have to copy all the data from the existing one level into the spaces for levels 2 and 3 and change the data so it is different.. tell me if you need more help.
