drop in control panel

Several numbers were not working on the touch pad. I ordered a new control panel, part # wpl5765mm432-60.
I removed the old one, which had two flat ribbon cables that I also removed. There were little caps that secured them to the contacts on the board .
I got them secured on the new one and tested it but it did not work. The clock works but none of the touch buttons that control the everything don’t. I uninstalled the new one and reattatched the old one and now that doesn’t work. What did I do wrong?
