(substitute your form name in here)

var l = document.formna me.elements.len gth;
for (var i=0; i<l; i++)
{
var e = document.formna me.elements[i];
if (e.type=="text" )
{
if (isBlank(e))
{
alert("Blank!") ;
return false;
}
}
}
return true;

function isBlank(strObje ct)
{
/* Returns false if the field has any non-space characters, true if
not.
You must pass in an input (text) object (not the value) */
var index;
var myChar;

if (! strObject)
{
return true;
}
else
{
var str = strObject.value ;
}

for (index = 0; index < str.length; index ++)
{
myChar = str.charAt(inde x);
if (myChar != " ")
{
return false;
}
}
return true;
}

Hey, if you got it flaunt it! If you don't, stare
at someone who does. Just don't lick the TV screen,
it leaves streaks.

Kaeli, I'm trying to modify your code (without success!) to check
document.all instead of a specific form. I now just need to see if any
input type="text" elements exist, not if they're empty. I won't bore
you with what I've tried cause it don't work!

Thanks again for your help.

Kathy
