Green machine

Hi. I've just bought a 97 Avensis 1.8 GLS automatic. The interior saloon light wasn't working so I changed it. When I put the bulb it lit up but it didn't look like it was in properly, so I took it back out and did it later. Now it doesn't work, along with the central locking also the trip meter and time clock return to zero every time I turn it off. I'm guessing it's a fuse, but which one and where?
