#showtooltip
/cast [target=focustarget, harm, nomod] [target=party1target, harm, nomod] [] lightning bolt
/cast [target=focustarget, harm, mod:alt] [target=party1target, harm, mod:alt] [] chain lightning
/cast [target=focustarget, help, nomod] [target=party1target, help, nomod] [] lesser healing wave
/cast [target=focustarget, help, mod:alt] [target=party1target, help, mod:alt] [] chain heal
I believe the first two conditions on each are fine, but the third is not implying the harn/help & mod conditions for your target, so it's always true. I believe changing it like so may be better:

Code:
#showtooltip
/cast [target=focustarget, harm, nomod] [target=party1target, harm, nomod] [harm, nomod] lightning bolt
/cast [target=focustarget, harm, mod:alt] [target=party1target, harm, mod:alt] [harm, mod:alt] chain lightning
/cast [target=focustarget, help, nomod] [target=party1target, help, nomod] [help, nomod] lesser healing wave
/cast [target=focustarget, help, mod:alt] [target=party1target, help, mod:alt] [help, mod:alt] chain heal
