[Edu-sig] problem with IF

[ken]

Thanks to all who responded to my problem.
I had tried to use a text string for the right side of the comparison 
and originally a between values, using AND set of decisions.  Also the 
original set of IFs was using elif but all had failed.
The thing tht finally worked was making sure that the numeric for wind 
dirn was as an int.  I thought I had used it as an int() previously and 
didn't look back at that 8-(
Anyway, a simple
dirn = int(dirn)
has fixed the problem 8-)
