Using a Macro to insert additional groups into a form

[john_london]

Hi Guys

So I have a form (screenshot attached)

This is a standard template that people have to fill in. The thing is, their may be more than one "TPR Contact" per form. As you can see there are four rows for the TPR Contact:

TPR Contact Name
TPR Contact Address
TPR Contact Phone
TPR Contact Email

What I hope to achieve is to use a macro to let the user insert a new contact, which will insert these four lines underneath for each contact. This should be able to de done multiple times and hopefully also be able to delete each contact. The problem is I have no idea how to even start! Any guidance would me most appreciated!
