OK, an update on the Mike Reumer Include Component plugin.
1. First, the reason I was getting an error is because I was not using the correct URL path in the plugin tag. I was originally using:
option=com_rsappt_pro14&view=Booking Screen GAD&Itemid=92 which I copied from the address bar in the top of my browser. I should have used:
option=com_rsappt_pro14&view=Booking%20Screen%20GAD&Itemid=92 which you can get by doing a right-click on your menu link.
2. Unfortunately, I still have another problem. When accessing ABPro from the plugin, if you click the 'Buy Now' button, instead of going to PayPal, the page simply refreshes. I asked Mike about it and this is what he told me:
The component is hiding the url for directing the post command. It's not set in the form. Maybe it's posting to the normal page url when calling the component directly. When embedding it in a different page with the plugin then the url is different and will redirect it to the frontpage of the site. Maybe you should ask the developer of the how you can set the url to post it.
I'm not smart enough to understand, so, Rob, I'm hoping that this means something to you.
EDIT: Sorry, I forgot to include a link to an example. Try this:
