can someone please help me with this as its driving me mad .

when the car is cold /inside he air con works fine,

as soon as the temp rises inside the car the aircon wont get cold !

ive had it re-gassed twice and has no leaks .

when you press the aircon button the revs pick up slightly as they should .

this is the first car we`ve had with aircon so its all new to me .

any help advise would be helpfull

cheers kev

Sounds like a classic case of evaporator temperature sensor failure...
