I request you all to please provide me the latest version of PDF as I am unable to find on net. The problem I am facing is to put the formula as given in the screen shot in the book.</div>
<div> I am unable to put the <b>formula</b> as described in JBOSS DROOLS BUSINESS RULES pdf file on page no. 102.....the formula is <b>salesValue-10 as the box is not capable of taking cahracters. </b>It is taking only integer.</div>
