what i'm trying create programme on predetermined commission rates based on how much in sales employee made input program.

i'm getting "cannot assign operator" error on

commrate=0.35 , monthlybonus=100000

, tells me i'll same error on rest of variables have been straight assigned numerical values amongst if nesting.

what doing wrong, here?

elif monthlysales>=100001 , monthlysales<500000: commrate=0.35 ; monthlybonus=100000

or

elif monthlysales>=100001 , monthlysales<500000: commrate=0.35 monthlybonus=100000
