Sublime Text 2 code snippet not working in proper scope

Question

I have just written the following snippet, and saved it in the folder Packages/User/HTML as "add-script-source.sublime-snippet."

<snippet>
    <content><![CDATA[
<script type="text/javascript" src="${1:script.js}">${2}</script>
]]></content>
    <!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
    <tabTrigger>scriptsrc</tabTrigger>
    <!-- Optional: Set a scope to limit where the snippet will trigger -->
    <scope>text.html</scope>
</snippet>

Now, I only want this snippet to work in HTML files, but it does not. If I comment out the "scope" tag, it will work in JavaScript, but still not in HTML. I was under the impression that the name of the folder beneath your User folder also gave Sublime Text the appropriate scope (as stated in this video https://tutsplus.com/lesson/your-first-snippet/), this does not appear to do anything. Whenever I set the scope tag to ANYTHING, the snippet does not trigger.

What might the problem be?

"just the helpful sublime text autocomplete doesn't appear, as it does in other languages. Does anyone know why this might be?"

You need to add this to your Packages/User/Preferences.sublime-settings file.

 "auto_complete_selector": "source, text"

Then give it a description in the snippet file:

<snippet>
    <content><![CDATA[
<script type="text/javascript" src="${1:script.js}">${2}</script>
]]></content>
    <!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
    <tabTrigger>scriptsrc</tabTrigger>
    <!-- Optional: Set a scope to limit where the snippet will trigger -->
    <scope>text.html</scope>
    <description>scriptsrc</description>
</snippet>
