what is wong with this counter for actiosncript?

on (release) { clickcounter = 0; if (valueNum == 20) { nextFrame(); } else if (clickcounter eq 0) { nextFrame(); nextFrame(); nextFrame(); } else { nextFrame(); nextFrame(); nextFrame(); nextFrame(); clickcounter += 1; } }

Each time i test scene and type any other value other than 20, it only play the else if one but never the else one. I want user to be given 2 tries to try guess and the answer. After 2 tries, a popup will be shown saying "Incorrect, the correct answer is 20."
