Can anyone tll me why i am getting pink colour casts on my white background. I am using on light on the background and one on the subject, can anyone advise what is the best tool on photoshop to correct this problem, i have been ussig the white selection tool in levels but it affects the whole image. kind regards, j

Not sure thats going to make a huge difference CB, quite often the pinkish tones are only in selective parts, often the forground.
Not convinced your lighting setups are quite there yet Realestate.
I suspect James may still be using JPEGs, where quite often if you get one colour right it has a bad effect on another colour. There is a bit more latitude with RAW in tricky lighting situations.
But I agree, it's probably his lighting set-up. However, his question was what to do about it in PS, which is not perhaps the best way for him to approach the problem!
I duplicate the layer and change the layer mode to screen and this sorts it out but jst feel it degrades the quality of the image. j
James... I'm NOT saying for one instance that this is an answer but, if you read through it and understand what is being discussed, it may provide you with some answers - certainly in terms of what and where there may be issues with your setup. (For your 'pink' situation, magenta is the problem in this link 
)
I've brought this to your attention because the OP is also a 5D user - as are all the contributors.
This may or may not be the answer... but... are you setting a custom white balance before each photoshoot? I usually plug my camera in to my laptop and set the custom white balance and check it straight on the screen and then make tiny adjustments to remove any colour casts visible on the laptop screen with the camera in the blue/magenta/yellow/green colour grid.
Im shooting in jpeg on flash white balance. I have never had this problem with my kids portraits but the other day when i was doing an adult model shoot and the lights were higher up i ended up getting pink casts, i thought the light was perhaps bouncing of something coloured in the room but could not think what so decided to ask on here. james
James, you most certainly have had this problem on your kids portraits as illustrated here
Was there not an earlier thread where people tried to help you eliminate this by use of an extra light or reflector?
Trying to fix this sort of thing in PS is probably not the way to go unless you really know what you are doing. Get it wrong and it could end up looking ten times worse.
I have recently learnt a way to correct a similar issue with an uneven spread of light on my paint splash shots, but it is not for the faint-hearted and involved asking detailed questions of a member here, reading a specialised book and a few frustrating attempts to get it right. Even now I only understand about 10% of the technique I was shown, the rest I put down to instinct to find the correct combination of layers/channels.
I wish you luck in solving it, but I think really you should be looking at your lighting set up and not a quick fix in PS after the event.
An additional light on the background would be good but i work in a very confind space so dont have enough room. I am positioning the background light very close to the background at far more than a 45 degree angle to try and get as much light as possible from one side to the other. j
I would suggest it's uneven light, slight under exposure, Nikon cameras and white balance being out.
All from my own experince before anyone jumps in the air. 
I know you shoot Canon
Don't have the problem now.

This seems like a good short term fix. The screen layer type wiill make the background white. Can you then not simply use a mask or history brush to bring back the model etc. However lighting seems to0 be the issue, and firing another light on the background at a 2 stop difference should give you a completely white background.

Maybe not enough space for a light on a stand, try a hotshoe flash unit fitted to clamp
