HI,
Could you post the form to a sharing site so that we can see how you have created the code as this may help us find a solution.
Steps to share a document..
1. Go to URL http://Acrobat.com
2. Create an account if you don't have one.
3. Then login to the website.
4. In top left corner you will see a button called Upload.
5. Click on browse and select the file you want to upload.
6. After Uploading, mouse over on the uploaded file. Click the down arrow button and choose Share document.
7. Then you will be prompted a popup window at the lower left corner. Choose "Publish it" option.
8. In the next pop up window choose "Copy Link" option.
9. You can paste the link in the forum thread.
Regards
Malcolm
