I am trying to teach myself JavaScript. I have tried using online tutorials, but I am not prepared for this kind of error. I am trying to have a tablerow appear when a checkbox is selected. The name of the tablerow is generated dynamically by PHP. My code is:

CODE
<head>

&lt;script type="text/javascript">
function showhide(box,id) {

    var elm = document.getElementById(id)

    elm.style.display = box.checked? "table-row":"none"
}
</script>

//Down in the body:

<insert type="checkbox" name="v1[]" value=$vname onclick="showhide(this,$vname)">


Unfortunately, I keep getting an "object required" error on the line with

CODE
elm.style.display = box.checked? "table-row":"none"


Any ideas? Thanks in advance for your help!

Ummm, yeah... found my own mistake. I was missing single quotes around the variable name that I was passing to the function. Thanks anyways!
