can not adjust cftextarea hieght

I have following code for my cftextarea and try to make the height and width I need for the form for the users.

For some reason, it does not change the size even I modify row and col parameters.

Is it something I am missing to adjust the height and width of cftextarea?

Your help and information is great appreciated,

Regards,

Iccsi,

<td><CFtextarea name="MytxtArea"  id="MyTextArea"  row="6" col="10"/></td>
