Easy Form Question

[lintz]

There will be such an easy answer for this but if I have a form which asks the user to delete an entry or not, how do I pass Yes/No into the form string?

echo  "<form name =\"form1\" method=\"post\" action=\"forums.php?delete_entry=(how to add yes/no here)\">

Do you want to delete this entry?<br>
<input type=\"submit\" value=\"Yes\">
&nbsp;&nbsp;&nbsp;&nbsp;
<input type=\"submit\" value=\"No\">
</form>";
