Checking dynamically named forms

[cathl]

Hi, I am trying to use Javascript to check a form which is named dynamically but my code isn't working. My cgi script creates a HTML page which contains forms named form0, form1, form2 etc. Each form contains a field named type_id, a field named budget and a field named start_date.
Here is my Javascript function:
function nextCheck(tot)
{
var missinginfo = "";
if (document.forms[tot].type_id.value=="&quot
{
missinginfo += "\n Budget Type";
}
if (document.forms[tot].budget.value=="&quot
{
missinginfo += "\n Budget";
}
if (document.forms[tot].start_date.value=="&quot
{
missinginfo += "\n Start Date";
}
if (missinginfo != "&quot
{
missinginfo = "Please fill in the following:\n"+missinginfo;
alert(missinginfo);
return false;
}
else
{
return true;
}
}

I am calling the function from the submit button like this:
onClick="return nextCheck(form$i);"
(where $i is a number generated by the cgi script)
Can anyone tell me where I'm going wrong? Thanks.

form1 or form3 or whatever isn't enough for the browser to find the element
either build the var in the function : eval("document."+tot)
or pass the actual form object <form ... onsubmit=&quot;return nextCheck(this)&quot;> (or if you want to keep calling it form the button return nextCheck(this.form)) ------

OK here is the solution I used:
function nextCheck(obj)
{
var missinginfo = &quot;&quot;;
if (obj.type_id.value==&quot;&quot
{
missinginfo += &quot;\n Budget Type&quot;;
}
if (obj.budget.value==&quot;&quot
{
missinginfo += &quot;\n Budget&quot;;
}
if (obj.start_date.value==&quot;&quot
{
missinginfo += &quot;\n Start Date&quot;;
}
if (missinginfo != &quot;&quot
{
missinginfo = &quot;Please fill in the following:\n&quot;+missinginfo;
alert(missinginfo);
return false;
}
else
{
return true;
}
}

and I called the function from the submit button using:
onClick=&quot;return nextCheck(this.form)&quot;
Thanks again!
