Thank you DR for your response. Yes that helps in a way, as that is what I am planning to do. But at the moment I can store the name of Projects, Categories and Specs in the three different models. Where can I store the values for the Specs for each Project? There is no table that contains that information. How can I set that table up... in a way that it can expand both sideways and downwards?
