I'm trying to create a web page that can be passed a
device name and then integrate that device name into
forms, links, and lastly show the status of the device.

I've got the links and form working...but can't nail
down the status. The section in red below is what
doesn't work. I'm guessing that my problem is that the
<% tags are not letting the inside run. I don't know
enough Java to really debug well though. Thoughts?

Here is what I have:

<script type="text/JavaScript"    Language="Java Script">
        var params =
document.location.search.substr(1,document.location.sear
ch.length).split('&');
        var arguments = Array();
        for(var i=0;i<params.length;i++) {
             var arg = params.split("=");
             arguments[arg[0]] = arg[1];
        }

           var myForm = document.TestForm;
           myForm.id.value = arguments['device'];
           myForm.NextURL.value =
arguments['back'];

           var TestVar =
document.getElementById("LinkOnTest");
           TestVar.href = "/ph-cgi/evalformula?
formula=ph_insteon('" + arguments['device'] +
"',iOn,255)&nexturl=" + arguments['back'];
          
           TestVar =
document.getElementById("LinkOffTest");
           TestVar.href = "/ph-cgi/evalformula?
formula=ph_insteon('" + arguments['device'] +
"',iOff,0)&nexturl=" + arguments['back'];

           var pageTitle =
document.getElementById("pageTitle");
        pageTitle.innerHTML = arguments['device'] || "";

           TestVar =
document.getElementById("Level");
           TestVar.src = "<%
if(ph_getinsteonlevel('" + arguments['device'> +
"')=0,'off.gif', if(ph_getinsteonlevel('" +
arguments['device'> + "')>245,'on.gif','dim.gif')) %>";


     </script>

Maybe the forum is killing your code, but you are missing closing brackets for the arguments bits.

Code:
TestVar.src = "<% if( ph_getinsteonlevel( '" + arguments['device']> + "')=0,'off.gif', if(ph_getinsteonlevel('" + arguments['device']> + "')>245,'on.gif','dim.gif')) %>";

Wait, I don't think that will work either.

The file is parsed when it's served. Your "arguments" reference doesn't mean anything at that point.

Unless there is code that passes that back which you took out for your post...

Forum killed my code. There are closing brackets. The
formula works perfectly if cut and pasted into PH. I
can take the <% %> off and drop that into text and it's
a formula that works perfect.

I think your second message is on target. It's an order
of execution. The Java is running on the client, and of
course PH is serving that page beforehand.

My question becomes...is there anyway to get returns
from a formula in Java?

My goal is to make a page that can be called from
anywhere to set the levels on a light. I've got a page
with 2-3 lights for the room in a table like this:

Name (on/off/dim pic)   ON +10% -10% Off

My goal is to make a link so you can do off/on from the
page, but to click the name and set to any level.

I'd *love* to have the page look up the status on it's
own, but if that doesn't work I might just pass it as a
parameter to that page. It's not quite as dynamic, but
it's something I could live with.

My lighting page reads the status on load using ph_getinsteonlevel and ph_getx10level.

Here is the thread. It's more complicated than what you need due to the sliders, but I think you can get some good info from it.
