Syntax error:Missing") " after the argument list.

Question

For some reason, no matter what i do, i can never use the addEventListener function, cuz i always get the same error. As far as i know all the () s and {} match each other, i have been thinking about it for 3 hours and cant figure out what's wrong :D it's driving me crazy :D the error is on line 3.

~ swim ~ notice g in the initial code?
It's not defined.

Note: I'm not solving the whole problem. I'm letting him think a little. It helps him understand better rather than doing the whole thing and he learns nothing.

He has to learn from his mistakes.

Answer 3

I figured out some of the errors.
Here's the code but it isn't completely debugged.
You have to figure out the rest. It's the least I could do.

Answer 5

Thank you for ur help and for letring me figure this out by myself :) i thought i was using g() as an Anonymous function which only exists inside the loop :)

Answer 6

Hmm so this is how i think:
. the correct format for an eventListener is var. addEventListener("event", f() {}) right? Well since the {} section was too long i have added tge)} at the end.

also how come grades is not defined? I have stated that grades=prompt earlier in the code?

i may be wrong tho, im a n00b :D
