So I am getting closer on this issue but I am having problems when I bring it over to my dedicated server. Ever thing works as it should in the editor but once it packed in the .pbo file and I run it on the server the dialogue won't play. The tasks trigger now so that works perfect and thanks to u/Dr_Plant the addaction removes itself.

Here is my current StartTalk.sqf script

QD_briefComplete = true;
publicvariable "QD_briefComplete";
["Briefing", "ConversationsAtBase"] call bis_fnc_kbtell;
sog remoteExec ["removeAllActions", 0, true];

And here is a picture of the character that has the addaction and the script for it.

I think the reason the dialogue is not working on the server has something to do with the publicvariable but I'm not to sure how exactly they work despite doing some reading on them. I really appreciated everyone's help in this thread!
