So is it possible to range value in if question?
if this is not right, is there any other way to do it
----------------------------------------------------------------------------
2. Can if have multiple questions? like this:
what you want to check if ww is in the range 1 to 10000 is
if ((ww>=1) && (ww <=10000))
2. Yes (see 1 above!). It is perfectly OK to omit the extra brackets as per your example, but if yuo start to get more coplext expressions you need to think about operator precedence - so I tend to always put the brackets in to make it clear (both to anyone reading the code, and to me, 6 months later:-)
