How do I incorporate relevant code in a webform someone created for me?

Hi

I had been using a webform someone created for me a while back who I’ve lost contact with. Before recently coming over to Infusionsoft, that form used Aweber code to get people’s name and email address. Is there a way that I can keep using that webform by deleting the Aweber code and adding Infusionsoft code? If so, how?

Thank you
Graeme
