Unable To Pass A Response Form Facebook To Another Function

If you view this question thank you in advance!, I am working on pulling data from Facebook. I am trying to pull the username from Facebook so i can use it in a later stage I have

Solution 1:

I think you are calling the function returndata() at any random point which you can't do. The reason is- the variable PASON is assigned value asynchronously. So, you have to code in such a way that you call returndata() after the value is assigned!

Its not quite clear what you are trying to do with the function returndata(). But, I hope your concept is clear now.
