I want to get the port input myself

Hello.
I’m studying real-time motion capture virtual YouTuber.

The VMC plug-in is being used.
The VMC plug-in can input a port from the blue print.

I want to enter the port after packaging.

Like a capture, I made an option menu.
I want to get a port input from the option menu and connect it to the port right away.

I don’t know how to create a variable that works with every blue print.

And I don’t know how to get that variable input.
(Making a text box, string to integer?)

Help me.

Is this right, guys?..
