Hi all, 

I am a beginner developer (really an admin but learning to build VF pages)
I built a page for the Account Object that I now need to move to a Custom Object and reference the Custom Object (School__C) fields. 
I cloned the Account page I built and changed out the Account wth School...I must be doing something wrong because I get the error 
"School Does Not Exist"
Can someone help? 
Code below

<apex:page tabStyle="School__c" standardController="School">
    <style >
        p {
        font-size:16px;
        }
        .beenWorkingOut {
        font-size:16px;
        }
        .paraCrunch {
        margin-left:10%;
        margin-right:10%;
        }
        a {
        text-decoration:none;
        }
    </style>
