I am working on multiple javascript if/else statements and they don't seem to be working. Only the Last part "Currently enrolled" is working. I am looking to get both the Yes and currently enrolled statements to work when a user selects from the drop down. The code I have is below:

```
function testBSN() {

if (document.getElementById('BSN').value == 'Yes') {
   document.getElementById('BSNQuestion'}.style.display = 'table-row';

} else {
   document.getElementById('BSNQuestion').style.display = 'none';
}   

if (document.getElementById('BSN').value == 'Yes') {
    document.getElementById('NSG_Grad_Yr').style.display = 'block';

} else {
   document.getElementById('NSG_Grad_Yr').style.display = 'none';
}   

if (document.getElementById('BSN').value == 'Yes') {
   document.getElementById('Est_NSG_School').style.display = 'block';

} else {
    document.getElementById('Est_NSG_School').style.display = 'none';
}   

if (document.getElementById('BSN').value == 'Currently Enrolled') {
   document.getElementById('BSNQuestion').style.display = 'table-row';

} else {
   document.getElementById('BSNQuestion').style.display = 'none';
}   

if (document.getElementById('BSN').value == 'Currently Enrolled') {
    document.getElementById('NSG_Grad_Yr').style.display = 'block';

} else {
   document.getElementById('NSG_Grad_Yr').style.display = 'none';
}   

if (document.getElementById('BSN').value == 'Currently Enrolled') {
   document.getElementById('Est_NSG_School').style.display = 'block';

    } else {
        document.getElementById('Est_NSG_School').style.display = 'none';
    }   
    }   

</script>

```

And here is the HTML for the section:

```
           <td style="padding-bottom: 10px" valign="top">  
                              <select name="BSN" size="1" id="BSN"     onclick='testBSN()'>
                                <option value="">Please Select</option>
                                <option value="Yes">Yes</option>
                                <option value="No">No</option>
                                <option value="Currently Enrolled">Currently Enrolled</option>
                          </select></td>
                          </tr>

                        <tr id="BSNQuestion" style="background-color: #0082c8; display:none">
                          <td valign="top" ><span style="font-size: 14px; font-weight:bold; font-family:Arial, Helvetica, sans-serif; color: #FFFFFF;">Year of graduation?</span></td>
                          <td valign="top" >&nbsp;</td>
                          <td valign="top"><span style="font-size: 14px; font-weight:bold; font-family:Arial, Helvetica, sans-serif; color: #FFFFFF;">From what school?</span></td>
                        </tr>
                        <tr>
                          <td valign="top">  <select style="display:none" name="NSG_Grad_Yr" id="NSG_Grad_Yr">

                <option value="N/A">Please Select</option>

                <option value="1950">1950</option>
                <option value="1951">1951</option>
                <option value="1952">1952</option>
                <option value="1953">1953</option>
                <option value="1954">1954</option>
                <option value="1955">1955</option>

              </select></td>
                          <td valign="top">&nbsp;</td>
                          <td style="padding-bottom: 10px" valign="top"><input style="display:none" type="text" name="Est_NSG_School" id="Est_NSG_School" size="32" /></td>
                          </tr>
