Multiple attachments with SendEmail

How can I add more that 1 attachment with SendEmail - only ever had to sent with one beofre and all goo but now i need to add 2 files.

QuoteSentFlag := null;
let thisBody := first((select Quote_Chasing).xQuoteLetter);
let myAtt := QuoteImage;
let myEmail := userEmail();
thisBody := replace(thisBody, "{xFirst}", text(eContact));
thisBody := replace(thisBody, "{Customer Ref}", 'Customer Ref');
thisBody := replace(thisBody, "{Quote Description}", 'Quote Description');
thisBody := replace(thisBody, "{Quote Number}", text(QteNum));
thisBody := replace(thisBody, "{Quote Date}", text(QteDate));
    sendEmail({
        from: myEmail,
        to: CustEmail,
       subject: "Your promo/print quote" + QteNum + "from 118 Printgroup",
        text: "Quote Updated",
        html: thisBody,
        attachments: myAtt
    });
