c1-c4 is count 1-4

its checking errors in my hangman program
4 correct you win
10 wrong you lose....

vposition is the location of the textbox and correct letter....

its still not working....

if(vposition == -1)count = count +1
if (count = 10)alert("you have lost, sorry");

How can count ever reach 10?

[Sensation]

for every wrong letter they get vposition is -1

10 of those they loose the game
