Creating Similar Fields In the Same Form!?

Hello All,
I’m struggling to create a particular form that has three segments (General details / Billing details / Delivery details), that each ask for similar field information e.g. each segment asks for ‘company name’.

I understand that the fields cannot exist in duplicate in the same form, otherwise they don’t capture. So, I’ve tried differentiating by giving unique IDs but this doesn’t seem to work.

I’ve copied the Form and the Mail info I have entered currently below, and would be very grateful if someone could advise what I am doing wrong and/or whether there is a workaround. Thank you in advance!
