On-use trinket macro

[Deleted]

Hello everyone,
Can somebody tell me the right macro to use a trinket every time is out of cd while casting Power Word: Shield? I know it can sounds obvious and I could look like a noob, but mine isn't working... Sometimes I cannot cast the spell if the trinket is still on CD (I noticed this happens especially if I am in a raid group). Thanks in advance.

This works pretty well for me:

#showtooltip SPELLNAME
/use TRINKETNAME
/script UIErrorsFrame:Clear();
/cast SPELLNAME

This will use both of your trinkets without an error message or character emote if they are not ready. COMPLETELY STOLEN from:

#showtooltip Power Word: Shield
/run sfx=GetCVar("Sound_EnableSFX");
/console Sound_EnableSFX 0
/run UIErrorsFrame:UnregisterEvent("UI_ERROR_MESSAGE")
/use 13
/use 14
/run UIErrorsFrame:RegisterEvent("UI_ERROR_MESSAGE")
/run SetCVar("Sound_EnableSFX",sfx);
/cast Power Word: Shield

First one doesn't work, I cannot understand why... Even inserting [@vuhdo] it does not always cast the spell if trinket is on CD.
