BindOBJ in behavior problem.

Hello! I don't know whether this is the right section. But here's my problem. I followed an example of how to make a character movement behavior, and everything was going fine. My character (Whom I've named Meelo) was able to walk in any direction on the screen. I was using the %val Boolean to see if a button was pressed for the normal movement keys and a run key (space), but then whenever I try to run up left it won't do it!
I have tried everything and searched all over this website but I couldn't find anything that helped.

I think it's either a problem with it can't detect five buttons at once. Because I've tried having a special case for Up and Left running. Without running it works fine, so I tried several things that proved that it was a problem detecting the running button. Any way any help would be HUGELY appreciated! This thing has been eating me for days. Here's the code:

if (!isObject(PlayerBehavior))
{
   %template = new BehaviorTemplate(PlayerBehavior);
   
   %template.friendlyName = "Player Movement";
   %template.behaviorType = "Player";
   %template.description  = "Gives the player movement ^u^.";

   %template.addBehaviorField(isPlayer, "Is this object the player?", bool,"False");
   %template.addBehaviorField(upKey, "What is the key to walk up?", keybind,"keyboard up");
   %template.addBehaviorField(downKey, "What is the key to walk up?", keybind,"keyboard down");
   %template.addBehaviorField(leftKey, "What is the key to walk up?", keybind,"keyboard left");
   %template.addBehaviorField(rightKey, "What is the key to walk up?", keybind,"keyboard right");
   %template.addBehaviorField(runKey, "What is the key you press to run?", keybind,"keyboard space");
   %template.addBehaviorField(runSpeed, "How much does holding the run key multiply your speed?", float, 2.0);
   %template.addBehaviorField(walkSpeed, "How fast can the character walk", float, 12.0);
   %this.currentY = 0.0;
   %this.currentX = 0.0;
   Echo("Operating start");
}
