Thank you for your help BrowserUk,I have another question regarding your code. How can I print (for eg) the values for channel number 1 for 'c'.I tried smth like this (it worked): 
$channels{1}[-1]{c}
$channels{1}[-2]{c}

[download]
but what if I want to be something generalized, instead of -1 and -2 to use an iterator?
