I would rather publish the 2 pages with forms in 2 separate tabs in Facebook. Furthermore, it will reduce the number of clicks for your visitor.
Thanks for your answer. Your suggestion will work but is not really what I am looking for.
Its important that we are able to distinguish between the 2 groups customer and candidates.
I feel that leading them to a single page with a selection will give us better data quality opposed to having 2 seperate tabs.
Maybe I do need to add something to the hyperlink URL ?
