I start a small project for a friend. We want to count passenger of a Lift for a wait time calculator
What should the program do?
Count the people
With a switch i send an input to pin 1,2,3 or 4 for my count system. The lift has 4 different speeds so he can transport more or less people.
belong to the speed the program evaluate status 1-3 1= less wait time 2= middle 3= many
send the status to a server so we can set a colour at a display (green yellow and red)
I have read many topics in the forum to come with the program so far but I can not get any further. Work with Arduino since a week so please be kind with your ratings. ;-D
Can anyone help me I would be so thankfull

You appear to be using an Ethernet Shield. Pins 4, 10, 11, 12, and 13 are used by the Ethernet Shield. Pin 4 is the Slave Select pin for the SD card slot on the Ethernet Shield. Things may go wrong if that pin is LOW. Try moving your 'pin4' input to some unused pin.
While you are at it, you should change the names to something like "Mode3Pin". It will make your code more portable if you add any functions that require you to move an input pin again.
You are not using any of the WiFi functions so you can comment out those lines at the top.

Done... thanks for that
My counter has already worked (3 days ago) but now nothing get displayed at the serial monitor and I think I have adjusted something the wrong way. Also the various modes do not work. Do you have ideas to help me?

That is rubbish. Pay attention to what a GET request looks like. It does NOT have embedded carriage returns and line feeds. It DOES end with " HTTP/1.0" or " HTTP/1.1".
And, all the stuff after the ? is name equal value pairs. Not some random crap.
I would be so thankfull
