fejl i lille kort kode

Hey, kan I umiddelbart se fejl i denne kode?

- den virker hvert fald ikke, og kommer med fejl.

------------------------------------------------
function box(type, name, value, onclick, width) {
if(type=="text") {
var input = '<input type="text" name="'+name+'" style="height: '+width+'px; border: none; -moz-opacity:1.00; background-color: transparent; font-size: 8pt; font-family: Verdana;">';
}else if(type=="button") {
var input = '<button onclick="'+onclick+'" style="height: '+width+'px; border: none; -moz-opacity:1.00; background-color: transparent; font-size: 8pt; font-family: Verdana;">'+value+'</button>';
}else if(type=="submit") {
var input = '<input type="submit" name="'+name+'" value="'+value+'" style="height: '+width+'px; border: none; -moz-opacity:1.00; background-color: transparent; font-size: 8pt; font-family: Verdana;">';
}
document.write('<TABLE BORDER=0 CELLPADDING=0 CELLSPACING=0>');
document.write('<TR>');
document.write('<TD><IMG SRC="images/box_left.gif" WIDTH=5 HEIGHT=18 ALT=""></TD>');
document.write('<TD background="images/box_middle.gif" HEIGHT=18>');
document.write(input);
document.write('</TD>');
document.write('<TD><IMG SRC="images/box_right.gif" WIDTH=5 HEIGHT=18 ALT=""></TD>');
document.write('</TR>');
document.write('</TABLE>');
}
}

- På forhånd..
