Hi,
You’re probably getting ‘-‘s because the plugin has no data to populate the link with.
There are two options:
1. Manually tell the plugin about the link you are trying to create by putting the info about the product in the shortcode, e.g.
[amazon asin=0123456789&title=Product Title&artist=Product Maker&price=$2.99]
Probably worth trying this just to make sure the plugin is working okay.
2. Get the plugin to retrieve the data automatically from Amazon when the link is created.
To do this you need to register with the Amazon Web Service (Advertising API). At the end of this process you will have two access keys which you put in the Amazon Link settings page. More details on how to do this are here: https://www.houseindorset.co.uk/plugins/amazon-link/getting-started/
Once you have done that turn on ‘Live Data’ and the plugin will get all the data needed to populate your template.
If you have a lot of Amazon Links, you probably want to enable the ‘Amazon Data Cache’ so that it does not have to get the data from Amazon every time someone visits your pages.
Hope this helps!
Paul
