Problems with multi. arrays/conditions

nickmiller24 (24)
I'm trying to make a simple tic tac toe game and I'm trying to make it so that if the user inputs any number not on the board not (1-9), that they recieve an error code. However, the underlined condition is turning out to be be false ( does not cout error code) no matter what number I input.

x = y assigns the value of y to x.
x == y is true if and only if the values of x and y are equal.
Check every if statement in xaxis() and yaxis().
