# Troubleshooting Implementation of the DSS
Please check the following items when troubleshooting the implementation of the DSS:
- Confirm that all instructions on the DSS wizard page have been followed, and the code snippets have been copied exactly.
- Make sure the DSS code does not reside within another
<form>element on the page.
- If the error, "'JSON' is undefined" occurs, a couple of things should be checked. Verify that the page has an opening
<!DOCTYPE html>tag. If a http-equiv meta tag is included on the page, it should indicate the latest IE compatibility. At the time of the writing of this documentation, that would be:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
