Hide table row with only name of input field

[TommyIndigo]

I have a select field I need to use to toggle visibility of other form fields. I am writing an onchange function to do this.

My problem is that the label for the field still appears...so I would like to hide the entire row. However, I cannot place an ID in the <TR> tag, as the form is generated BEFORE it gets to the code I am writing (I am just writing the validation and toggling script and have no control over the form html).

Can I possibly hide a table row WITH ONLY THE KNOWLEDGE OF A SINGLE FORM ELEMENT NAME?

Any advice would be most appreciated!!

If it is helpful, here is the relevant code I have so far.

		alert('This is NOT a formal decision.  Unused fields should be hidden.');
		
		//Identify the list of fields associated with formal decisions
		var FieldList = new Array(
			  	'DecisionTeam',
			  	'ProblemStatement',
			 	'EvaluationCriteria'
  				);
			  
		 //Loop through DAR fields and hide
            	var FieldListLength = FieldList.length;
	    	var counter=0; 
	  	for (counter=0; counter<FieldListLength; counter++) 
	  	{ 
		  var CurrentFieldName = FieldList[counter];
		  var FormFieldExaminedString = 'window.document.forms[0].'+CurrentFieldName;
		  var EvaluatedField = eval(FormFieldExaminedString);
		  EvaluatedField.style.display = 'none';
		}

how about this?
<tr id="nOP" style="visibility:hidden;">
<td>something</td>
</tr>

then you can
var obj1 = document.getElementById("nOP");

if (something happens)
{
obj1.style.visibility = "visible";
}
else
{
obj1.style.visibility = "hidden";
}

hope it helps

Thanks for the quick reply, but unfortunately I can't change the incoming HTML tags. That is generated from a 3rd party software vendor (who did not use IDs for their <TR> tags

The only info I have to use is the NAME attribute of the INPUT tags. So far I can hide the field itself, but just not the row it resides in. Any ideas?
