If you used a script intended to display a single timer you are probably experiencing "interference" between the scripts. Most likely, the script uses a couple of variables to keep track of key values. If you do not rename these varaibles in one of the scripts they will cancel eachother out. (Even if they are placed in different <script> tags.)
It's not possible to tell eaxtly why it's not working because you haven't included the actual script in your post. Use [code ] [/code ] wrappers for that or post a link to it.
<script>//change the text below to reflect your own,
