You have to select your marines by dragging a box around them. Once you have the ones you want to give the waypoint to, right click where you want to place the waypoint. If you get an "invalid order," try clicking a nearby location.
You can give different waypoints as well:
Clicking the ground gives a "Move-to" waypoint. Clicking an unbuilt structure gives a "Build" waypoint. Clicking a built structure gives a "Defend" waypoint. Clicking an enemy unit or structure gives an "Attack" waypoint.
Hope this helps, and welcome to the boards! <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' valign='absmiddle' alt='smile.gif'><!--endemo-->

lol U can also sometimes put a waypoint on a soldier, say Guard soldier at Wp or something. but this can be annoying for the person with it on them. Not sure if its bug or what. Also had build hive @ WP <!--emo&???--><img src='http://www.unknownworlds.com/forums/html/emoticons/confused.gif' border='0' valign='absmiddle' alt='confused.gif'><!--endemo-->?? lol
