How to change MX records in GoDaddy?

I have bought some domains from goDaddy. My emails are hosted on different server and I want to change the MX records.

In the dashboard, I do not see any link to modify the MX records.
So, at least to me, their documentation page is wrong or old.

There is a link to modify nameserver only.
Which too does not work with the emails.

Help me please.

Login to the domain management console
-MouseOver the DOMAINS tab and click My Domains
-Select the domain you want to modify
-On the Details page click ‘Total DNS Control and MX Records’
Here you can modify existing MX record OR add a new MX record for a particular domain.

Thanks gho!
The actual URL I reached was:
https://tdns.secureserver.net/index.php
There I could see the list of records.

I fixed it now.

I think for you as for any customer of them that should not be a problem at all to call them and ask for the help. Why are you trying to solve everything by yourself?
In any case I’m happy to hear you have fixed everything with them though.
