I tried inserting the code the way you explained but it came up with an error. That’s ok, there is only so much that you can help me with. Unless you are interested in doing some work on the side with this? (PM me if you are interested).
The other thing you mentioned is the membership plugin, which I actually already have. I purchased the eStore and eMember plugin as a set and got both up and running. I just couldn’t find any functionality in either plugin which would allow me to restrict non-members from purchasing certain products. Of course I can hide an entire page with products in it but that would mean that visitors won’t be able to see what great products we have for offer. It’s complicated because we are an alternative medicine clinic, and we cannot sell products to every person who walks in from the streets. Only clients.
So if anything more comes to mind please let me know or PM me. Otherwise I will continue looking for someone on elance.
Thanks.
