Hello I'm new to editing .aspx files and was hoping someone could give me a few pointers. I'm trying to add 3 additional fields when a customer creates an account. They would not be required but I would like the info visible when I view a client on the backend. I would like these fields to come after the phone number so that if a customer was a member of a particular organization they could enter their member ID.
I'm looking at createaccount.aspx and seeing the line regarding phone info that reads
PhoneCaption="<%$ Tokens:StringResource, createaccount.aspx.23 %>
What I'm not sure of is the function of the red numbers (in this case 23) and what else I may need to edit.
