how create input that active constant number(IMAGE INSIDE)

I did simulink blocks that send nubmer 5 and 6 in separately.i put "if" block before them that will active and send 5 or 6 if the input of the "if" block is <1 so it will send 5 otherwise it will send 6.the problem is that i cant connect to the blocks that send 5 and 6, because i start with constant nubmer that has only possibility to output.Proposals for solving please
