Making flip-flops using logic gates in Proteus – I’m getting gray (unknown) signals

for my school project i have to use Proteus to design my circuit. My professor told us that we cannot use any flip-flops and if we had to use them we should make them by using logic gates. I’m trying to make JK flip flops but I’m getting gray signals in the areas shown in picture. Can someone help me how can I get this flip-flop to work?
