Problems with arguments

Hi:

I read carefully all the documentation about using arguments with Views Slideshow and I try to replicate on my own slideshow .. with no effect.

I try this:

1. Create a Wiew with some stuff
2. Add a field on Arguments (Node:Title: Display all values)
3. Add this code in the argument Handlingt Code
   $view->slideshow['timer_delay'] = 3000

With any result.

Looks like there I made a mistake at a very low level of the use of the arguments, so anybody could drop some light?

Thank you a lot
