HIDE/SHOW function is not working - are my products tagged correctly?

Question: I've applied HIDE/SHOW tags to some products using the walkthrough here but these products aren't being hidden/shown correctly?

Answer: Please note that all Shopify tags are case sensitive so your HIDE/SHOW tags must correspond to your exact discount group title.

In the example below, let's assume our discount group title is Special.

Incorrectly Tagged Example :

The example product shown below is incorrectly tagged with special-SHOW and so will not function correctly with our HIDE/SHOW function. 

How do we correct this?

Correctly Tagged Example :

As mentioned above all HIDE/SHOW tags must be case sensitive and correspond to your discount group title - so in this case we just have to amend this tag to Special-SHOW and then Save it.
