I'm new to this, and stole/doctored my code from the "Ugly JavaScript
Handbook"
I have a slide show program.
First theres stuff to set up the array, and the time between slides
Then a function startIt()is defined
then a function stopIt()
Then two buttons, Start and Stop, which when pressed call the relevant
functions
When the page loads, you have to click the Start button to get the
slide show running, but I'd like it to start running straight away
without having to click.
I can't for the life of me figure this out.
I thought it was just a question of putting the line
startIt();
in the appropriate place.
Here's the whole of the code
Thanks
Tony

Thanks
There's a logic to that!
Maybe I should buy a book to get me underway.
Does JS have public variables, and scope and stuff like that?
