How can I click the Send button In Webbrowser

this is the HTML from the page:

<td align=right><font size=2 face=arial,geneva color=000000><input
class="btnDsp" type="button" onClick='onSend();' value='Send'> <input
class="btnDsp" type="button" onClick='saveDraft();' value='Save Draft'>
<input class="btnDsp" type="button" onClick='spellCheck();' value='Spell
Check'> <input class="btnDsp" type="button" value='Attach'
onclick='onAttach(); return false;'> <input class="btnDsp" type="button"
onClick="location.href='splash.php?ArdSI=881e80cb5f0bf1a97b99d4d2bbb6cf76'"
name="cancel" value='Close'></font></td>

Can I click a button when I only have the Value and not the Name?

Any help is greatly appreciated.
Thanks
