Strange button output

Hi,
I'm building a loadcell right in this moment and i took a button to change between grams and kilos. When i write Serial.println(digitalRead(Button)) the Serial Monitor is printing 0... All right. But when I push the button down the Serial Monitor stops printing and when i pick my finger up, the serial monitor prints 0.00 or -0.00
Never had this any time before..
Would be nice if you could help.

Greetings

Ok you need to post a schematic of how you have wired up your button and you need to post the code you are using.

Only then can we know what you have done and we have a chance of seeing what you have done wrong. Use the copy for forum option in the IDE’s edit menu and paste into the reply box.

It looks like your button is shorting out the power supply somehow.
