Awesome help, the sort integer thing is something I've seen on here in other people's code but not understood until your reference. Thanks once again for the great advice :)

Hello, I'm not really sure what the "fixnum" requirement means - I'm using Javascript.
I've tried converting to int and float a variety of ways and always pass the value test but still fail: "TypeError: Cannot set property '0' of undefined at multiplicationTable"

Can anyone offer a bit of advice?

Thanks!

Hey guys, this is ongoing for a number of days now.I've completely restarted this from scratch five times now and google a billion ways of finding out if an array is null. It is clear to me now that array2 in test five is null and as indicated in the comment above I can return any random thing OTHER THAN false (ie, 5, 0, -1, even the string "false" <- which does not satisfy the test) without getting a timeout error. This is Extreeeeemely frustrating now!!

I'm having a really strange issue where I can't return false without getting a timeout error! (using javascript)

I can return 4 or "elephants" or "false" and the test completes fine but as soon as I type: return false;
I get an error

this is after an if statement:
if(array2 == null || array1 == null)
{
return false; // once again, here return 4; or return "false"; work no problem... :/
}

Thanks for any advice you can offer!
