Flash Button To Submit ASP Form

[HomeAway]

Hi there,

I have a flash movie that allows a user to upload a photo to customize his "home" page. In my flash movie i have a button that when clicked runs the following
getURL("javascript:submitIT()"

then inside my html page i have a javascript function for submitIT as follows
function submitIT(){
document.upload.submit() -- where upload is my form name.
}

everytime i run this i get an access denied error on that line. All the form does is post the file path to my ASP page where i deal with the upload and save of the file.

<form name=&quot;upload&quot; enctype=&quot;multipart/form-data&quot; method=&quot;POST&quot; action=&quot;complete.asp&quot; style=&quot;visibility: hidden&quot;>
<input type=&quot;file&quot; name=&quot;file&quot; size=&quot;20&quot;>
<INPUT TYPE=&quot;submit&quot; VALUE=&quot;Upload&quot;>
</form>

If i run the submit from the form and not through flash it works. Please help.
