I've finally got stuck delving into Statamic, and hope someone can help me! I have a collection (in this case 'QA' for simple question and answer text) which I want to dynamically restrict to a particular tag, chosen via a fieldset value on the page.

The variable is 'qa-tag' and this is what I have so far:

{{ collection:qas taxonomy:tags="{{ qa-tag }}"}}    
        <h3>{{ title }}</h3>
        <p>{{ answer }}</p>
    {{ /collection:qas }} 

Is this possible?
