About Wavrecord, please help!! My program requires the user to input the length(r) and choose the sampling frequency(g). But in here, it does not detect the value of g. Program can be found below

It's hard to say what's happening without seeing the code. From your description and the error messages, I'm guessing you have a callback to obtain r and g, then a callback to do the recording (using those values). So can you please post the code for those two parts of the application.
