HELP! Error Message keeping me from editing fields

HELP! Error Message keeping me from editing fields

I edited 2 existing forms: "RTO Listings View" and "RTO Sellers View" and created a new view called "Shannon - RTO Listings"
 
Now I am unable to edit any of these entries/fields for these 3 views.  All the other views are fine.
 
For example, I go into RTO Listings View, I pick any file to edit, I don't make any changes and just click UPDATE. 
 
An error message comes up saying there's an invalid field (which has happened to me before when I forgot to complete a required field)...
 
When I scroll down to see which field needs to be corrected, at the bottom it says View Error Details...I click it and it says "java.lang.Long cannot be cast to java.lang.Double"
 
Any idea what I did wrong and how to fix???
