Hey guys, long time no see

My game is almost ready, but I'm having a problem with global variables, not as simple as just setting them as the title sugests

So, here are some ways the global variables do work

_global.mywar = "yay";
_global.mywar = 10;
_global.mywar = _global.mywar + 10;

No problem there, however, if I have a var, called "score" which keeps track of player points, and have a "totalpoints" var, which keep these points as a form of in-game credit, but I can't do this:

if(at the end of the level)
{
_global.totalpoints = _global.totalpoints + score;
}

It doesn't work. So how am I suposed to add the numeric value of the "score" var to my global variable?
