Holy prism focus macro not working

[Axyos]

Looking for help on a macro that should target my focus, else target my target. I'm using : the (at) is the actual symbol, but the forums won't let me post it...

#showtooltip
/cast [(at)focustarget,exists,nodead][] Holy prism

In not sure what is wrong, but it will never target my focus, only ever my target

Your macro will cast Holy Prism on the Target of Your Focus, not on your focus

try

#showtooltip
/cast [(at)focus,exists,nodead][] Holy prism

Sigh, thanks

Target when appended to something is referring to the target of that unit.
So focustarget is the target of your focus.
As Thakah pointed out, just shorten it to focus.
