Who can help me, pleas?
All Systems and browsers akcept this code, just...
i have no idea, why Netscape on mac don't do this program:

browserCheck();
macCheck();
var a = pfad;
if ( mac =="ja" )
{
if (browser=="ie5")
{
document.write("<LINK REL=\"STYLESHEET\" HREF=http://www.webdeveloper.com/forum/archive/index.php/\"",a,"technic/sr_css/sr_mac_ie5.css\" TYPE=\"text/css\">"); // css items for mac Browser IE5
}
else if (browser=="ns4")
document.write("<LINK REL=\"STYLESHEET\" HREF=\"",a,"technic/sr_css/sr_mac_ns.css\" TYPE=\"text/css\">"); // css items for mac Browser NS4
}
else
{
if (browser=="ie5")
{
document.write("<LINK REL=\"STYLESHEET\" HREF=\"",a,"technic/sr_css/sr_win_ie5.css\" TYPE=\"text/css\">"); // css items for windows Browser IE5
}
else if (browser=="ns4") document.write("<LINK REL=\"STYLESHEET\" HREF=\"",a,"technic/sr_css/sr_win_ns.css\" TYPE=\"text/css\">"); // css items for windows Browser NS4
}

.....

May be "document.write" is false for that?..no Idea
