drop down changed

Still learning here.
What i’m try to do is, take two dropdowns side by side with a row of ten. Then try to count how many rows were changed when both dropdown are changed, then count it as 1 value per row. To be displayed in a text box.

[CODE]


<table border=1>
<tr>
<td colspan=2>
<center><input type=”text” name=”” id=”Date” size=”10″></center>
</td>
</tr>
<tr>
<td>
<select size=”1″ onchange=”update()” name=”” id=”PA1″>
<option value=”00″>Select</option>
*<option value=”0″>No Change</option>
</td>
<td
<select size=”1″ onchange=”update()” name=”” id=”PC1″>
*<option value=”00″>Select</option>
<option value=”0″>No Change</option>
</td>
</tr>
<tr>
<td>
<select size=”1″ onchange=”update()” name=”” id=”PA2″>
<option value=”00″>Select</option>
<option value=”0″>No Change</option>
</td>
<td>
<select size=”1″ onchange=”update()” name=”” id=”PC2″>
*<option value=”00″>Select</option>
*<option value=”0″>No Change</option>
</td>
</tr>
<tr>
<td>
<select size=”1″ onchange=”update()” name=”” id=”PA3″>
<option value=”00″>Select</option>
*<option value=”0″>No Change</option>
</td>
<td>
<select size=”1″ onchange=”update()” name=”” id=”PC3″>
*<option value=”00″>Select</option>
*<option value=”0″>No Change</option>
</td>
</tr>
