Reply to GamePad axis problem

Hello guys,
Today I started working on my new game pad controller. I am waiting for my arcade buttons and pots to arrive so i had only one potentiometer and some pushbuttons.
The problem is this: after i soldered all the wires on the gamepad pcb, when i pluged the game pad in my laptop, in the gamepad advanced properities appeared like someone was playing with the joysticks, that point that show the intersection of the axis
It is possible that all of that happened because i did not have pots? Or i broked the pcb?

I want to point that the buttons works fine, the only problem is with the potentiometers.

Thank you in advance and sorry for my bad english, i am from Romania. I hope that you will understand what i mean
