VLAN 200 must be have in the same subnet,ex,PC1(192.168.1.1),PC2(192.168.1.2),you can try again.
First thing I can see is that
SWITCHA Vlan200 192.168.1.1/24
SWITCHB Vlan200 192.168.2.1/24
Are in differnet subnets. Change SwitchB Vlan200 to 192.168.1.2/24 then you can ping SWITCHA from SWITCHB
I just realized that, they are in different subnets. I will try it again
