Mouseover macro

[zoot]

Trying to come up with a single macro to handle all my tier 5 talents. I thought I might have it with this but it doesn't seem to work. Any suggestions?

/cast [@mouseover,help,nodead,talent:5/1][talent:5/1]Living Bomb;[@mouseover,help,nodead,talent:5/2][talent:5/2]Unstable Magic;[@mouseover,help,nodead,talent:5/3][talent:5/3]Blast Wave

I'd also settle for a mouseover macro for just living bomb.
