HTML, set iframe src as a javascript variable

Question

I would like to display a window in my webpage of another webpage, hopefully via iframe. I need to set the src as a javascript variable, here is the code:

<html>
<head><title>my webpage</title></head>
<SCRIPT language=JavaScript type=text/javascript>
function GoToURL(j) {
var URLis = document.URLframe.Dest.value
document.write("<center><iframe src=\"http://www.example.com\"/ width=1350 height=500     seamless></center>");
    }
</SCRIPT>
<FORM name=URLframe>
<TABLE align=center border=0>

<TBODY>
<TR>
<TD vAlign=center align=middle><BR><INPUT maxLength=50 size=50 
  name=Dest></TD></TR>
<TR>
<TD align=middle>
  <P><INPUT onclick=GoToURL(this) type=button value="                       Go to..                                " name="Go to"></P></TD></TR></TBODY></TABLE></FORM>
</html>

I need to set the iframe src to the variable URLis, simply put. I am somewhat of a newb in both html and javascript, so please keep as simple as possible. Do you have any suggestions or ideas for a way to set the iframe src as URLis variable?

Thank you.

Why cant you just target your link to that iframe?

Try this:

var URLis = document.URLframe.Dest.value;
document.write('<center><iframe src="' + URLis + '" width=1350 height=500 seamless></center>');
