Raise Dead not working

[Rebel_ZhouYu_Wu]

im making a map an i made a copy of raise dead with a few things changed.
the range is 99999
the cool down is 20
the durnation is 3600
the mana cost is 0
the unit type two is skeleton archer
My probelm is when i click on spell it says there is no usable corspes nearby when there is.

Are the corpses behind shroud? Is the spell ability in the object editor set for dead units?

the corspes were spoted by another player's tower they were in plain site the caster was a building the corspes consited of night elf archer stacked on top o each other and the spell was on auto cast.

I think i found out the problem the reason is that when there is a corspes right next to it it works but the reason it didnt work for corspe far away from it is that the system that checks for a usable corspe scan the area close to around it not the etire area of the cast range so there for if there is a corspe far away it wont cast the spell.
