Trouble making a Custom Healing Spray and a Cluster Rocket

[ezxariarch]

I was trying to make a custom spell that uses healing spray as a base that damages instead of heals. I Set the DAMAGE AMOUNT field to all negative numbers, thinking that since possitive numbers heals, so negative must do the opposite. That did work. So I tried to make it a healing spell instead, by resetting everything back to possitive. The healing spell didnt do anything either. I dont get what the problem is. No matter what i edit, the spell simply doesnt do anything besides having the cool effects.

So I tried using the Cluster Rocket as a base since they all use that SPRAY PROJECTILE effect. I set the damage to 10/15/20 and the damage intervals to .2/.2/.2 (so they will deal 5 times the damage amount per second). I didnt want the spell do stun anyone, so i set the DURATION fiels to .01 (since 0 doesnt work and tends to make the buff last forever). I tested the spell out, and it didnt do any damage.

Can someone tell me what I'm doing wrong and/or tell me a solution?

I've already test it, i don't have such a problem. Negative values deals damage and when I change the values back, it heals area, nothing wrong. Try to reset the ability, i mean you reset healing spray ability to default not just reset some fields.
