Hi there i have this code to in a URL to add details in to Thunderbird email that works on all the fields exept the attachment field will not attach my Pdf-Image, could someone tell me what i'm doing wrong i used to use SEND TO but not everyone got the mail or it would go into there spam folder thank you in advance.

    let 'Pdf-Image' := importFile(this, printAndSaveRecord(this, "Invoice") + Customer.CUSTMER.'First Name' + ".pdf");
    printRecord(this, "Invoice");
    openURL("mailto:" + Customer.CUSTMER.'Master Email' + "?cc=" + Customer.CUSTMER.'CC-Email' +
    "&subject=" +
    'Email-Subject' +
    "&body=" +
    'Email-Body' +
    "&attachment=" +
    url('Pdf-Image'))

end
