Hi Dave,

There aren't any emails in the Cc slot so I imagine that part is fine, I will definitely edit the extra quotes though I made the mistake of thinking it was just google being google.  For reference , I'm running Python 3.x.  I'll try out putting the quotes around it.   The full code is:

>>> def phi_m(x,m):
      rtn = []
      for n2 in range(0, len(x)*m - 2):
        n = n2 / m
        r = n2 - n * m
        rtn.append(m * x[n] + r * (x[n + 1] - x[n]))
        print 'n2 =', n2, ': n =', n, ' r =' , r, ' rtn =', rtn
      rtn
      
SyntaxError: invalid syntax

where the second apostrophe in 'n2 =' is marked in orange.  Thanks to everyone who's helped out so far, hopefully with some experience I'll be able sort out any syntax issues that come my way.
