DIVIDE BY ZERO ERROR, WHEN RUN FROM ASP PAGE

Here is the scenario, i have a stored procedure, it calculates
commissions and runs fine in SQL. However when the SP is run through
my asp page it will come back with a divide by zero error, but only
for one sales person... I have been through this code a hundred times
and can't find any errors. Any help would be much appreciated.

SP:
