Solution 1

I can see one problem in the code.
That is the starting script tag is missing.
Your whole JavaScript Code should be inside script tags, but there is no start tag of script.

Just above the code var Type;, you should have one script tag like <script>. You have one end tag for this, but no start tag.
Please add this.
