Hi All,

Need help please.  Im not a developer and so struggling with the followng issue: 

I have created a custom object which behaves in a similer manner as the "Quote" standard object and so i am able to produce Quotes in PDF by clicking on a custom button called "Create PDF".  However, when I produce the PDF file i would like to incremant the file name by '1' each time.  For example, when the "Create PDF" button is clicked the file name should be Quote_V1.pdf should then become Quote_V2.PDF,  then Quote_V3.PDF etc etc

Not sure how to do this.  Please see a part of my apex code below which is where I think i need to make my modification :

     Public PageReference SaveQuote()
    {
        try
        {
            String QId = ApexPages.currentPage().getParameters().get('id');
            dealerQuotation = [SELECT Id,Name FROM Dealer_Quotation__c WHERE Id = :QId]; 
            PageReference pdf = Page.Dealer_Quotation;
            pdf.getParameters().put('id',Qid);
            
            Attachment attach = new Attachment();
            Blob body;
            try
            {
                body = pdf.getContentAsPdf();
            }
            catch(Exception ex)
            {
                body = Blob.ValueOf('Error occured in page');
            }
            string name;
            if(dealerQuotation != null)
            {
                name = dealerQuotation.Name + '.pdf';
            }
            else
            {
                name = 'Quotation.pdf';
            }
            attach.body = body;
            attach.Name = name;
            attach.IsPrivate = false;
            attach.ParentId = QId;
            insert attach; 
            PageReference redirectPage = New PageReference('/' + QId);
            redirectPage.setRedirect(true);
            return redirectPage;    
        }
        catch(Exception ex)
        {
            ApexPages.Message exMsg = new ApexPages.Message(ApexPages.Severity.ERROR, ex.getMessage());
            ApexPages.AddMessage(exMsg);
            return null;
        }    
       
    }

Any help would be greatly appreciated!
