I am struggling to send emails from a button.

the current code is:

let check := dialog("Email Guest?", "Guest Will Receive a Confirmation Email.", ["Email Confirmation", "Close"]);
if check = "Email Confirmation" then
    let myPdf := printAndSaveRecord(this, "Maintenance Log");
    let myName := "Maintenace Report.pdf";
    importFile(this, myPdf, myName);
    let myEmail := userEmail(user());
    sendEmail({
        from: "email linked to user",
        to: whomever i want,
        subject: "Maintenance Report",
        text: "Maintenance Report",
        html: null,
        attachments: file(this, myName)
    });
    alert("Confirmation Sent")
end
