Answer 2

It doesn't work perfectly on your phone. You should try to remember this; but this is because the page hasn't loaded yet. To avoid this, you should put the variable declarations in the window.onload function.

Answer 3

Airree do I window.onload through the whole javascript or, just for the variables at the top?
can you remind me how you do it again - is it
window.onload = () => {
javasceipt

}

is it like that ^ ?

Answer 4

It's not necessary to put the whole javascript in the code. The only thing you must do, is the variable declarations (also don't use any keyword, so they will have global scope)

Answer 5

Airree , could you please tell me at what line i would place the closing tag of the window.onload (i assume opening starts at the top windo...{ clos?)
because i put the closing at bottom, and couldn't find var..., also tried it before the first function, ' couldn't find variable'
.?

Thank you
