If you are trying to show druid spell icons on your paladin, you'll have to manually pick each icon from the 'new macro' list. I don't believe there is a way to have it switch between druid icons unless you're on the druid. If you're trying to do this on a druid then....

#show (or #showtooltip) has to be all on 1 line, and at the beginning of the macro.
Personally, I use [mod] instead of [modifier] to prevent typos & save characters

Spells with ranks I believe need to be identified:
Spell(Rank 5)
or
Spell() -this will use the highest rank learned
Spell without ranks only need the spell name, not a rank

So a macro may have the first line like this:
#showtooltip [nomod] SpellA(); [mod:alt] SpellB(); [mod:ctrl] SpellC(); [mod:shift] SpellD()

I don't recall if the separated for each is a semicolon ; or if its just a comma , so try both to be sure.
Can also try taking the [nomod] out of the first spell, but I don't think that'll have the desired results. Might just show SpellA icon for all.
