form

I have a basic html form that adds some data to the page using PHP. I want to make this form field a "Price" field. My html is:
<input class="bids" name="comment" id="comment" tabindex="4" />
How can I fix this field so that users can't enter random letters, dollar signs, dashes, or other weird formats. I want the output to be whole dollars. Sorry I'm a complete programming moron. :)
