Okay, so I’ve figured out why there was only “x8 (textarea)” form fields in the mapping section. So it looks like I don’t need to use hooks? I’ve changed the form fields to the following:
[textarea x8high_school_education default:user_high_school_education]
[textarea x8vocational_training default:user_vocational_training]
So now all the fields are showing up in the mapping section

But now when I submit the form, none of the fields (even the normal text fields) are being mapped. It is not even naming the post correctly. With only text fields mapped (no textarea fields), the post was named correctly and the data was mapped correctly.

Please help!
