{% if page.url == "/tag page" %} add custom meta description, Help Please

Hi,

I want to display custom meta description on some tag pages. (e.g. https://caqaresources.com.au/collections/assessment-kit/Assessment-Kit-(Q ) and I try to use a construction like:

{% if collection.handle == 'assessment-kit' and collection.tags contains 'Assessment-Kit-(Q)' %}

{% endif %}

This is not working Please someone can help me find the right solution? Thank you!

That looks like it should work if the collection has that tag/handle combo, but since the handle is checked why check the tag also? Maybe only check if collection exists and then the tag without the handle.

can you please, rewrite the code?
