Hello, I'm trying to connect keypad, but I have problems even with creating of circuit. 

I have errors like this - " Two or more connected terminals have mismatching types. All connected terminals must have the same type (i.e., all analog or all digital). Remove the incorrect terminal(s) and replace them with the correct type"

I'm newbie in this and rly hope for  your help.

Here is scrshot of my project.

You did not check for your pins the option "external Terminal".

As a consequence you used to connect your (external) switches to the (chip-)internal side of the pins. External wires are always in blue.

So how I should improve that situation?

Replace input pins with output and connect to external terminal, or what ?

The port/pins component 4 types digital input, digital output, digital bidirectional and analog you have to right click on the pin and it opens the configuration screen make sure they are all digital or analog per your design.

As a starting point, look at this (way to make a) component.

That's cool, but as I see, it's full component which I can use. There is a problem, I have fullworking project with little bit another realization of  keypad. But now I want to create my own, because using someone project never make me better in that area :)  and it;s very hard to find out how it works through borrowed one.
