Only the 1st and the 2nd condition working rest not working.

error msg:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in D:\xampp\htdocs\cycle\find.php on line 72.

use $result = mysql_query($sql) or die (mysql_error());

if you have an error in your query it won't be executed and this is why you get that message.

//If user only enter Bicycle Type
elseif (($brandC="") AND ($typeC!=="") AND ($styleC== "All") AND ($frameC== "") AND ($groupSetC== ""))

I do this occasionally. You are confusing the comparison operators. On line 39, where you have $brandC="", you're not comparing the string to empty, you're resetting the value to empty. If you want to check if empty, use $brandC =="". Also, $typeC !=="" should be $typeC !="". There are also similar problems on line 45 & 51.
Or better yet, use

elseif(empty($brandC) && !empty($typeC) && empty($frameC) && empty($groupSetC))

I could be wrong, but, I believe it will parse a bit faster.
