Hi @tigerfish
Looks like you need to add in a meta_query arg to the query.
To get you started, please read the guide for filtering posts:
http://www.advancedcustomfields.com/resources/how-to/how-to-query-posts-filtered-by-custom-field-values/
After you have read and understand the above, please have a search around for “query posts after date custom field” – you should find plenty of threads on google!
Cheers
