Cars plugin hide some fields with some category HELP

[bstruik]

Hi there, i was wondering if you can hide some fields when you post a new ad with the cars plugin when you select a other field then cars. Let say ... when i post a new ad and i select airbags... then i would not like to see the number of doors etc, but but i only want to see the car brand and make?

I am not a programmer, so if anyone can help me on the way with wat to adjust in wihch .php file i would be verry happy!

i changed it myself. in al the carsplugin php files i removed the fields that i dont need. Then i used the custom fields.
