Electrical fault please can anyone HELP?

[houston]

I 've been trying to install a radio/cd unit in my Sport. I've caused an electrical short behind the radio opening of the dashboard. I check the fuse box and found that fuse no 28 (30amp ) had blown which i have replaced.
Unfortunately the following things are still not working:
Rev Gauge
Fuel ecomony gauge
On board computer
Interior lights

Anyone got any ideas where to start? All other fuses in the fuse box are ok.

any help grately appreciated

Have a closer look at fuse 21.
Can you reduce the size of your avatar a little, please.

thanks for your help, you were right a very slight break in the fuse number 21. That was the easiest electric fault i've ever fixed!!! Usually shout ,curse followed by an expensive trip to the auto electrician, very grateful.
