How to attach multiple file to send mail command

Hi,
i want color effect on mail as well as multiple attachment.I have code but this code is used for single attachment. I am unable to attach more than one file.:wall:
I want to send two attachments -ahmed.csv and ahmed1.csv .
Sample content:

<html>
<body>
<b> Hi...</b>
</body>
</html>

Final code:

#!/usr/bin/ksh
DIR=/appldata/download/mail
export MAILTO="abc@xyz.com"
export SUBJECT="Report"
export BODY="$DIR/sample.html"
export ATTACH="$DIR/ahmed.csv"
export ATTACH1="$DIR/ahmed1.csv"
(
 echo "To: $MAILTO"
 echo "Subject: $SUBJECT"
 echo "MIME-Version: 1.0"
 echo 'Content-Type: multipart/mixed; boundary="-bon"'
 echo
 echo '---BON'
 echo "Content-Type: text/html"
 echo "Content-Disposition: inline"
 cat $BODY
 echo '---BON'
 echo 'Content-Type: application; name="'$(basename $ATTACH)'"'
 echo "Content-Transfer-Encoding: base64"
 echo 'Content-Disposition: attachment; filename="'$(basename $ATTACH)'"'
 uuencode --base64 $ATTACH $(basename $ATTACH)
 echo '---BON--'
) | /usr/sbin/sendmail $MAILTO

No.
mutilple attachments:

(uuecode file1.oldname file1.newname; uuencode file2.old file2.new) | \
  mailx -s 'subject goes here '  user@someplace.com me@mycompany.com

If you want color, send an html file.
Multi + color text message:

(uuecode file1.oldname file1.newname; uuencode file2.old file2.new) | \
  mailx -s 'subject goes here '  user@someplace.com me@mycompany.com \
< mymessagefile.html
