I have a form where we have a field "Job Profile" which is mapped to "Job Profile" field in Marketo database, the form has "select" type for this field with 5 options. The last option is "Other", whoever chooses "Other" will get another Text Field to Write their answer. How will I get this text box value in same "Job Profile" field in Marketo Database.?
Any help would be appreciated.
You should definitely check out Sandy's article, where he explains how to use the Rich Text field on the form to add and capture the Other value in the same field without having to add an extra field for it and then write data to the original field (if at all required, like in your case).
If you strictly want to use a dedicated field for capturing non-standard (other) values and write it to your original Job Profile field, then you'd have to use a smart campaign (Change Data Value Flow Step) or use Marketo Forms JS to append the data in the other field to the Job Profile field and then post data to Marketo.
