ok so the solution, first u make a GET to the page and look at the response headers, one is a b64 encoded string, decode that and it says to add a number parameter or something so then u add a number param and get another clue which is a base32 encoded string, decode that then u get a snippet of php code saying u need a number between 90000 and 99999 for the flag so then u try 90055 or something but thats too small so u add a load of 0's onto the end to see if that works and it does so 000000000000090055 will give u the flag
