passing arguments from scale widget to function

[m7b52000]

Problem solved. use 'command = Calc' to call my Calc function but ignore 
the argument passed to it. Create a list with the following elements - 
a.get(), b.get() and c.get(). Every time a scale slider is moved, Calc 
will retrieve the current scale values and I can do with them whatever I 
want...

Now to work out how to write the answer to a text box or similar.......

Thanks for your help, Matt
