We have a Table where we need to highlight a given row when the user holds their mouse over that row.

I have added the CSS code:

.tb_find {
background: #FFFFFF;

.tb_find:hover {
background: #C8DAEF;

and then added to the
table <tr> definition:

<tr bgcolor="#ffffff" class="tb_find">

however the row is not changing background color when the mouse is held over the row!

What do we need to do to correct this?
