i got the marker showing on the taks by using

Code:
["Task1","Task1Title","Task1Desc",true,["mrkTaskMM1",getmarkerpos "task1","","","text1"]] call SHK_Taskmaster_add };
the orange is the code for the marker

now break it down


mrkTaskMM1 = the type of marker to show

task1 = is the marker you have on the map for the task area ( this is needed becouse taskmaster will spawn its marker at this position)

text1 = you can change that to what ever you want to be typed beside the marker in game on the map

hope this helps someone
