And it is not even accessed before it manage to change the value of looptwo, could it be something broken in javascript handling nested loops and if clauses? This if clause if encapsulated on its own so it should not present a problem if not accessed, i can not see how it can change the boolean looptwo.

You can see what happens if you do not heed sound advice.

Global variables are just as difficult to maintain as space cargo ships.
Both can blow up in your face.

It start at middle of base 6 and looptwo should be true until 11*12 but somehow it magically manage change the boolean.

The code do not differ from code below that works, except for that if clause that not even accessed at the point it magically flops the boolean looptwo.
