Creating autogenerating rows in Word forms

Question

In Word 2003, I am trying to create a form that can generate additional entries if the person filling out the forms requires them. I have tried a form field that runs a macro on entry but that does not seem to be working. Is there a more elegant way to make a form that can add rows in Word as the user requires?

Essentially something like this (as an unrelated though functionally accurate example):

When the "Click here" is clicked is generates another exactly the same.

Any help would be greatly appreciated.
