Why is my Hidden value not being assigned to my input text?

Why is my Hidden value not being assigned to my input text?

I've got this HTML:

  1. <input type="hidden" id="BLAhfuseremail" value=" warble.p.mcgorkle@geewhizmail.com">
    <input type="text" id="BLAboxemailsection1" value="bla">

...and this jQuery:

  1. $('[id$=boxemailsection1]').text('[id$=hfuseremail]').value();
I also tried:

  1. $('[id$=boxemailsection1]').text('[id$=hfuseremail]').valueOf();
...expecting (or at least hoping) that the boxemailsection1 "textbox" will be assigned " warble.p.mcgorkle@geewhizmail.com"

It's not happening, though; boxemailsection1 retains the "bla"

How can I get the hidden val into boxemailsection1?
