Hi;
I've written this code:
 
<html>
<body>
<span tal:define="global number here/quotes/randomNumber"></span>
<table><tr><td>
<span metal:use-macro="here/en-us/quotes/?number/macros/quote"></span><br />
</td></tr></table>
</body>
<html>
 
...and here's randomNumber, which is an External Method:
 
def randomNumber(self):
   return randrange(1, len(self.objectValues()), 1)
 
but it throws this error which ends with "Iteration over non-sequence". Well, 
the folder from which it's supposed to select a quote holds nothing but a 
sequential number of page templates (named 1, 2, 3...). What am I doing wrong?
TIA,
Tony
