RobotStudio event

couple of Rbotostudio programming questions

Hi, I am pretty new to robotstudio and our robot welder installation is not yet complete and I need to complete some programs beforehand.
I have just got few simple questions to ask:
1. A warning "argument reltool is delcared as LOCAL in a different module. the configuration is not verified" is given for everything with reltook, I have used reltool before and after welds.
2. "No template found for instruction" error when trying to sync VC to station with the path when I am trying to get two welds together. For example: I want to weld a "L" defined by 3 points target 10, target 20 and target 30. My path was ArcLStart target10 ,  ArcMoveL target20 and ArcLEnd target30. I am assuming that the correct operation would be ArcLStart target10, ArcLEnd target 20, ArcLStart target20 and then ArcLEnd target30? 
3. I have 2 stations set up with external axis, Is there a function that will just move station 1 to a custom defined position just to get out of way when working on station 2? Where can i get a list of built-in functions that available to users? It is greyed out when i go right click --> go to definition for any functions.

Any help would be appreciated.
Regards
Kent
