The next code, isn't working - a function which will configure few variables (onclick) and insert them to a function.

Code:

function defineVars() {
var ca1=document.getElementById('c1').value;
var cb2=document.getElementById('c2').value;
var cc3=document.getElementById('c3').value; 
var cd4=document.getElementById('c4').value;
var ce5=document.getElementById('c5').value;
var cf6=document.getElementById('c6').value;
var cg7=document.getElementById('c7').value;
var ch8=document.getElementById('c8').value;
var ci9=document.getElementById('c9').value;
var cj10=document.getElementById('c10').value;
showUser(ca1, cb2, cc3, cd4, ce5, cf6, cg7, ch8, ci9, cj10);
}

The code only works when I delete the ".value" from the variables.
The elements (Text boxes) that the javascript search for are placed on the same page.
The javascript code just gets the value of the elements and assign a variable for it.
Then the variables are inserted into a function (Which will launch ajax code).
if I change the function to this:
showUser('ca1', 'cb2', 'cc3', 'cd4', 'ce5', 'cf6', 'cg7', 'ch8', 'ci9', 'cj10');
(not variables used)
and I remove the variables from the code, it works perfectly.

Thanks for helpers

When do you call defineVars? Because you have to wait for the document to load before it will work.

(And they definitely have ID's as well as names right?)

It's essential to paste the complete code in situations like this, and almost all others as well.
Nobody can tell you exactly what's wrong if all they can do is guess.

Since you say it works if you change the call to showUser('ca1', 'cb2', 'cc3', 'cd4', 'ce5', 'cf6', 'cg7', 'ch8', 'ci9', 'cj10'); I'm guessing the showUser function has its own way of getting a reference to the elements you need. It's possible that the showUser function accepts either an element id, or a direct reference (and is able to act accordingly) since you say it works if you remove the .value parts.

And if "it works when I do X", why don't you just do X?

FOUND THE PROBLEM.
You are right, I was needed to post the whole page.

Some of the elements that the Javascript searched for, aren't exists on the page.
I didn't knew it will damage the code!

Sorry for spending your time, and thanks.
