Vector Bus Line problem, cant connect input output pins

Ok so im new on this forum, and actually im new in the world of FPGA. And im starting to learn, but im stuck with graphical design.

VHDL is simple i get it, but when using vectors in Graphical Design i always have errors that i pin is not connected.

Now i use the bus line to connect, and i designated the input pin as vector for 3 bit combination.

I also added a picture of my screen, hope you can help me.

I have to do it in graphic way because its a must for college work, in VHDL it would be so simple :)

Thanks in advance.
