Hide a table row if the data field is empty

Question

I know this sounds easy and it would be if I were doing it with my own data.
But I'm writing html that is being copied into an online form processor call "Absolute Form Processor" to be used to generate a report within in the software.
It works great if I create every row in the table but I'd like to hide the rows that don't have a field value so that the report is more concise.  I hope that makes sense.
The data accessed by surrounding the field name with "$$".  For example:  $$ed2_1$$.
What kind of script do I need to write to hide a row if there's no data?
Here's the code:
<table width="95%" border="1" cellspacing="0" cellpadding="5">
                <tr>
                    <th colspan="2">Education and Experience Information</th>
                    </tr>
                <tr>
                    <td width="18%">School/Experience:  </td>
                    <td width="82%">$$ed1_1$$</td>
                    </tr>
                <tr>
                    <td>Degree/Position:  </td>
                    <td>$$ed1_2$$</td>
                    </tr>
                <tr>
                    <td>Major/Minor:  </td>
                    <td>$$ed1_3$$</td>
                    </tr>
                <tr>
                    <td width="18%">School/Experience:  </td>
                    <td width="82%">$$ed2_1$$</td>
                    </tr>
                <tr>
                    <td>Degree/Position:  </td>
                    <td>$$ed2_2$$</td>
                    </tr>
                <tr>
                    <td>Major/Minor:  </td>
                    <td>$$ed2_3$$</td>
                    </tr>
                <tr>
                    <td>School/Experience:  </td>
                    <td>$$ed3_1$$</td>
                    </tr>
                <tr>
                    <td>Degree/Position:  </td>
                    <td>$$ed3_2$$</td>
                    </tr>
                <tr>
                    <td>Major/Minor:  </td>
                    <td>$$ed3_3$$</td>
                    </tr>
                <tr>
                    <td>School/Experience:  </td>
                    <td>$$ed4_1$$</td>
                    </tr>
                <tr>
                    <td>Degree/Position:  </td>
                    <td>$$ed4_2$$</td>
                    </tr>
                <tr>
                    <td>Major/Minor:  </td>
                    <td>$$ed4_3$$</td>
                    </tr>
                </table>
Any help would be most graciously accepted.

Hi
try this
<%
'Check a variable isn't "empty"
Function IsBlank(ByRef TempVar)
     'by default, assume it's not blank
     IsBlank = False
     'now check by variable type
     Select Case VarType(TempVar)
         'Empty & Null
         Case 0, 1
             IsBlank = True
         'String
         Case 8
             If Len(TempVar) = 0 Then
                 IsBlank = True
             End If
         'Object
         Case 9
             tmpType = TypeName(TempVar)
             If (tmpType = "Nothing") Or (tmpType = "Empty") Then
                 IsBlank = True
             End If
         'Array
         Case 8192, 8204, 8209
             'does it have at least one element?
             If UBound(TempVar) = -1 Then
                 IsBlank = True
             End If
     End Select
End Function
%>
Example usage
<%
If IsBlank("Degree/Position:")Then
     Response.Write "the default text or nothing goes here"
End If
%>
You could also use "if ¦IsBlank" to only include the item if it has content, to do what you require.
