Hi Team !

           Since yesterday only I started learning Drools with the help of Google and JBOSS DROOLS BUSINESS RULES pdf file. I faced many problems to understand the concept but now its going smooth. But the problem is the version of PDF file of the book and the Govener version. Its quite different.  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.
           I am unable to put the formula as described in JBOSS DROOLS BUSINESS RULES pdf file on page no. 102.....the formula is salesValue-10 as the box is not capable of taking cahracters. It is taking only integer.

Thanks in Advance for all the help and material !!!!
