To import yahoo contacts in the web application (yahoo API)

You have already asked this question. There is no point in repeating the exact same question again - in fact it annoys people so you are less likely to get a usefull answer.

Also, may I refer you to item 4 on the screen where you entered your questions, it says:-

4. Keep the question as concise as possible. If you have to include code, include the smallest snippet of code you can - do not dump your entire codebase.


It is a lot to expect busy people to go through all this code when all you say is it is not working - in what way is it 'not working'. If you cannot narrow the problem down to a smaller peice of code at least describe the problem in greater detail (preferaby do both).

If you can do that I am sure someone will be able to give you some help with this problem. :thumbsup:

Best of Luck :)
