this block schematic when i program and test input using switch and output using seven segment..

when i represent 1 number convert to bcd will be 0000 but seven segment as output not represent 1.

Seven segment to be a=1,b=0,c=0, d=1,e=1,f=1,g=1

i want result a=0,b=1,c=1,d=0,e=0,f=0,g=0

what wrong with my seven segment
