Hi @Dana_Vinci and welcome to the Forums!
@Getz_Pro does a good job at providing some guidance on how to map form submissions to a specific field. The only thing I would add is a link to the Asana Guide article on Custom Fields.
Also, here is another post on theforumss created by @Mike_Tammaro outlining how he created and uses Asana Forms for Customer Satisfaction Surveys.
Hopefully this is helpful, but if you have further questions, feel free to post them here in the comments!
Cheers,
Matt
