LOL! ;D
The only correct syntax in this whole thread has been in MorMel's post
Not trying to put anyone down here, but all you need to do is check out the official command reference if you're after correct syntax.
You can do this using either a trigger:
TriggerRadius: 0,0
Condition Field: (getdammage
unit) > 0.1
OnActivation Field: playmusic "signs"
or with scripting commands:
- ? getdammage unit > 0.1 : playmusic "signs" (already mentioned)
- if (getDammage _Unit > 0.1) then {playmusic "signs"}
Sorry guys, I probably shouldn't have stuck my oar in here. It just frustrates me to see someone with a question getting (slightly) wrong advice.
Not meaning to rub anyone up the wrong way, I'm sure as hell not god's gift to scripting... ;D
But if you are ever in doubt about syntax, all you need to do is have a quick peek at the Official Command Reference
