Hi guys/gals

This is a long one. I like to work in mission building. I am haveing trouble with warping. I have instruction from on older dite with these instructions using 6WPs an example. WP1=Never Warp (start mission), WP2=No Warp, WP3=Warp, WP4=Warp, WP5=No Warp and WP6=Always Warp (final waypoint). I have placed a check in the warp box for WP3 &4. I then greated a trigger for each (player reached WP), I then greated en event for each (player reached WP). When I press the X I warp to WP3. After that each time I try to warp I get the message Warp disabled. What  am I doing wrong. I have spent almost 10 hours trying every combiniation I can think of. Help Help Help!!!!
