How to make a click effect cost mana?

[Pallos]

ok Current mana -15000 Worked !

but how Can I stop the clickie from being used without the required mana, IE if mana is Less than 15k Id like the clickie to not be able to cast the spell, any ideas?

What im trying to prevent here is chain casting of a custom pet without putting a recast timer into effect.


thanks for the help, wish the spell editor was a bit more intuitive
