If $size_input is printed correcly, them it has been passed to the
wanted_1 fine and the problem is elsewhere.
The "condition" for the push() looks insanely complex, I bet you made
a mistake there.
And to tell the truth .. with the number of global variables you have
I don't understand why didn't you use $size_input as a global
variable as well.
