Hiding the Submit Button based on the Drop Down Selection

[freeza]

Hello there,

I am looking to hide my submit button from my Form if specific selections are made within the drop down of the form. How can I make this work? Please direct me to the correct path as this is my first time trying to execute such a thing. 

In this form, if a person selects Agency/Consultants, Apply to be a contributor or Support for current contributors the form Submit button should disappear while a message pops up. I was able to hide the rest of the fields and get the message appear using the visibility rules. But I am not sure how to make the Submit button disappear once either of those selections are made. 

Thank You!
