lol.
 
who would think two ppl will post exactly the same
problem on one night? have you read selwyn's post? 
it's about the same thing.. using symbolic initial
conditions.  ( i think) 

is the tutorial on your website where i can download
and check out?  if not, do you mind posting it when
you are ready? 

thanks a bunch
