attachMovie problem

i have inserted this code into my button game


on(release){
	if (score>=200){
	attachMovie(secret 200,popbutton,depth,initObject);
	}
}

whenerver i test it i get this error report.

Error Scene=Scene 1, layer=Layer 1, frame=1:Line 43: ‘)’ or ‘,’ expected
attachMovie(secret 200,testFlash,3,initObject);

Error Scene=Scene 1, layer=Layer 1, frame=1:Line 45: Unexpected ‘}’ encountered
}

Total ActionScript Errors: 2 Reported Errors: 2

what’s wrong? I don’t get it, and what am I supposed to put in depth and initOnject

on(release){
    if (score>=200){
    attachMovie("secret_200","popbutton",this.getNextHighestDepth());
    }
}

Also you can not have spaces in movieclip names. See secret_200 above.
