Jonathan – thanks for all your assistance and hope everything is ok.
Disregard this Post. I needed to check the save terms to post option for the taxonomy custom field
I did as you recommended and the taxonomy does now show the categories that can be selected but these are not put to the post once it is created. I mean the form creates the new posts but they still list as Uncategorized in the post info. The ACF taxonomy field is keeping the selection from the fronted form but I am looking to use the standard WP categories like under each post the theme lists the category associated with that post.
