difference between asp dundas on sever2003 and winxp

[goaganesha]

Hi There,

Here is something that's way to weird for me to understand. I have a form for an emailtool on the website. I'm using dundas aspmail and upload component. Here on my local pc (iis on winxp) the whole thing works fine. As soon as I upload the page to a windows2003 server the weirdest things happen:
I test checkboxes with isEmpty like in this example:

Set objUpload = Server.CreateObject("Dundas.Upload")
if isEmpty(objUpload.Form("check_po")) then
response.write("empty")
else
response.write("checked")
end if

On my local pc empty checkboxes give "empty" but on the server they give "checked"
Also the isEmpty is the only way to do the test on the remote server. using:

if objUpload.Form("check_po") ="on" then
...

will give an http500 error while on my local pc this works fine.

Does anyone have an idea what could be wrong 'cause It's freaking me out.
