implant extra information users for autofill forms

what is the code to get the information from the custom extra fields into a post or form?

I found this code for example:
<input type=”hidden” name=”cimy_uef_TEL_1_prev_value” value=”0611874298″/>
<input id=”cimy_uef_1″ class=”regular-text” name=”cimy_uef_TEL” type=”text” value=”0611874298″ maxlength=”13″/>

But when I use that as a code for any user it will not display the information of that particular user. So what can I change that it will work and display the right user information?

I want to use this to autofill a contact form made with the contact form 7 plugin.
On this page there is a test page of the form; http://www.paragliding-holland.nl/aanmeldingsformulier-test/

I hope someone can help me with this.
