I you call your php page directly from your browser does it return the
desired XML file? And with your ID parameter?

Hello list,
First off, hi all. I subscribed to this list yesterday and ive seen
alot of good posts already, so there's little doubt that anyone can
help me out ;)
A little introduction:
Since a few weeks i'm hired at an Internet Development company in
town, and my job is primarily xhtml/css development.
Yet, the very first project I am doing requires a jpg-viewer flash
app. Last week ive been studying books, and code of friends to build
what i am building right now, and one of the final steps has got me
stuck.
so, here we are:
[actionscript is in the bottom of this email]
I am making a flash movie that loads 10 jpeg files from a xml feed,
generated by a phpfile.
Its purpose is to act as a carrousel that loops the jpegs over the
screen.
The feed shows the last 10 uploaded jpegs if no parameters are set. If
you pass it a parameter called PictureID, it'll give you the jpeg
with the given ID plus the 9 jpegs uploaded prior to that.
(ie. feed.php?PictureID=20)
i am having php echo the given PictureID to html as in this:
<params name="flashvars" value="PictureID=20">
in the actionscript i am retrieving that with _root.PictureID.
Next step is to load the 10 jpegs that come before(10-1) the
curently(20-11) loaded jpegs.
And here i am having trouble, please checkout the function attached to
the button, in the bottom of the script.
First i'm emptying the arrays and unloading currently loaded jpegs.
I then want to reset the PictureID to 10 lower than the current value
and 'start all over again' with the new range of jpegs.
Except, at 'loadXML' nothing happens.
So can anyone please help me, or give any insights on how this should
be solved?
[p.s. i could also do a getURL() to the page itself and pass the
feed.php a new parameter, but we dont want to make it look smooth.. ]
Many thanks in advance,
Sibrand Hoekstra
