I am new to Apex and I am having trouble with changing the record type of a record on a visualforce page.  Here is what is happening.


If I try to use this as an Apex Class,
 

public class LoadRecordType {

    Account a;
    
    public LoadRecordType(ApexPages.StandardController controller) {
        a=(Account)controller.getRecord();
    }
    
    public PageReference setRecordType(){
        a.RecordTypeId=[Select Id,SobjectType,Name From RecordType where Name ='VCHospital' and SobjectType ='Account'  limit 1].id;
        update a;
        return null;
    }
}

And reference this extension on the visualforce page like this.
 

<apex:page standardController="Account" extensions="LoadRecordType" action="{!setRecordType}">
    <apex:detail subject="{!account}"/>
</apex:page>

I get this error.

Visualforce Error
System.QueryException: List has no rows for assignment to SObject
Error is in expression '{!setRecordType}' in component <apex:page> in page accountdetailbutton: Class.LoadRecordType.setRecordType: line 10, column 1
Class.LoadRecordType.setRecordType: line 10, column 1

Im kind of a visualforce Newb.  Can someone help me figure out why this is happening?

I want to have a visualforce page open a standard account detail view except write in code that defaults the twistsections as hidden so the sections are collapsed by default.
