Writing Programs with Multiple functions (Edit)

icefalcn (8)
hi, i recently wrote some code for a school project and before i start this question, i am not asking you to do this for me, i have just encountered an error that i would like your advice on

anyways,
we were instructed to make a program that would simulate the dice game "pig"

what i would like to know is why my code insists on giving the player one turn,
then the computer turn, and then give the player two turns, and give the computer one turn, and then again give the player two turns, and give the computer one turn

i know my question isn't phrased the best i would really appreciate some help!
thank very much =)

here is my code:
