Dynamic field names

#1

Is there an easy way to create two hidden fields, one for field_name (list) and the other for field_value (number), and concatenate these into a visible field where field_name=field_value? Sorry if I’m missing something basic here’s the schema: https://www.mockaroo.com/schemas/353096

Thanks!

Is this what you are trying to do?

You can create hidden fields by prepending the field name with a double underscore.

__fieldname
