How choose in a pop up window and the value be updated in the parent window

[amrigo]

Hi

I hava a form with a select box named theme and need to open a window with a list of themes with each preview image and a button to choose the theme.

Clicking on the button will close the pop-up and update the value of the theme select box

How can it be done ?
The button to open the window with themes is working fine
<input type=button value="Choose theme" onClick=window.open("choosetheme.php","w","width=100,height=100") >

But the problem is on the button to choose the theme it is not updating the value of the theme select box

<input type=button name=themeselected value=$theme->name onCLick='parent.window.getElementById(\"theme\").value=".$theme->name.";'>

Thank´s in advance

Hi

Using this function still does not work

function sendValue(s){
alert(s);
//var selvalue = s.value; //options[s.selectedIndex]
window.opener.document.mform1.getElementById("theme").[selectedIndex] = s;
window.self.close();
}

Inside a radio button i call : onClick='sendValue(this.value);' and does not work

But using onClick='alert(this.value);' shows the right value

What can it be ?

Now it is working:

function sendValue(s){
window.opener.document.getElementById("mform1").theme.selectedIndex = s;
window.opener.document.getElementById("mform1").theme.text = s;
window.opener.document.getElementById("mform1").theme.value = s;
window.close();
}
