Michael,

There must be some bad data in the database for JNPR.  The following Max 
function,
Max(0, -1869, hi ), works as designed for JNPR.  But change Max to 
Max(0, -1879, hi) the Max function doesn't return any data.  The Max 
function also doesn't return an data whenever you go back more than 1879 
days.  Hence if you had chosen to only go back 373 weeks you would never 
had seen this problem with JNPR..
