ok, so i have this movie clip, that i am having duplicate and give the dynamic name of (“butt” + g), g being the variable. i need to later reference this number for that button name. so i was doing this bigpic=String(this.\_name); r=bigpic.charAt(4); which was working fine, up until i got up to number 10, the first two digit number. since it was only pulling the 4th character, it was reading anything in the teens and 1 and anything in the 20’s as 2. now is there a way to pull one, or two numbers from this string? or can i have it pull the string name - butt? ---

i would name them "butt\_" + the number… then to reference later: bigpic=String(this._name); tRef = bigPic.split("_") r= Number(tRef[1]) this way you will always get the full number back correctly. ---
