ipod not scrolling

I have an iPod 5th-gen video. I have replaced the battery and click wheel on it and everything is working EXCEPT scrolling. I can reset it and everything but I can not scroll. I don't know if I have to 'ground' the wheel's cable better. I know there is glue on the bottom of the second cable so that it sticks to the metal of the case. Please Help. I appreciate it!!!
