Hello,

This may seem like a dumb question. I am new to Flex 3 and truly kind of new
to developing. I have a lot to learn and books are my source of information.
So, here is what I did and what happens.

I created a new Flex Project, added a folder called 'assets' to the project.
Then I created a new .css file and placed it in the assets folder. First
problem: when the .css file was being created i get an message that CSS files
can only be created within a project source folder. I don't want it there so I
moved it to the assets folder. This is according the book I am currently using
"Flex for Designers". I used the Flex Style Explorer site to create my CSS.
And pasted it into the .css file. I added the style source to my main.mxml and
get the following error: Problem finding external
stylesheet:/assets/customstyle.css. Shouldn't I be able to have that .css
file and really any images or other assets anywhere within the project as long
as my pathing is correct? And although I do get the error, the CSS does apply
to the mxml. So why do I still get the error?

Thanks in advance for your advise.
