Hi, I'm working on creating a visual force page for a custom object I created. When I go to save it, it says that the standard controller is unknown. So what I'm trying to do is create a page from the Sales Coaching object which is record type specific which you'll see in the coding below. I then have a few sections on the screen. Within each section I have a field set, as well as writing that I want in each section. Below you'll see the apex class and VF page I'm trying to save. Any assistance would be greatly appreciated.

Thanks!

Apex Class

public with sharing class salescoachingRedirect {

    public String retURL {get; set;}
    public String saveNewURL {get; set;}
    public String rType {get; set;}
    public String modeType {get; set;}
    public ApexPages.StandardController sCtrl;
    
    public salescoachingRedirect(ApexPages.StandardController controller) {
        this.sCtrl = controller;
        retURL = ApexPages.currentpage().getParameters().get('retURL');
        rType = ApexPages.currentPage().getParameters().get('International Sales Coaching Note');
        String recordId = ApexPages.currentpage().getParameters().get('Id');
        if(String.isBlank(recordId)){
            modeType = 'Edit';
        }else{
            modeType = 'Detail';
        }
    }
    
    public pageReference save(){
        this.sCtrl.save();        
        String recordId = ApexPages.currentpage().getParameters().get('Id');
        pageReference rPage = null;
        if(!String.isBlank(recordId)){
            rPage = new pageReference('/'+recordId);
        }
        modeType = 'Detail';
        return rPage;
    }
    
    public pageReference openEditView(){
        modeType = 'Edit';
        return null;
    }
    
    public PageReference redirect() {
        PageReference returnURL;
        // Redirect if Record Type corresponds to custom VisualForce page
        IF(rType == 'International Sales Coaching Note') {
              returnURL = new PageReference('/apex/Sales_Coaching_Note__c');
        }
        return returnURL;
    }
}
