To anyone who may be able to help,
I need to calculate the distance between two zip codes and all is working except for the square root part.
I have been trying to use
<dtml-var expr="_.sqrt(x)">
to get the square root of x. But it does not work and reports an attribute error. I have used the _.int(x) with no problem and dis notice the sqrt() is in the Math Library. Is there additional syntax to access this function? I searched and googled and found everything but an example in DTML of how to use sqrt().
See http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixA.stx especially the part about "modules" in DTML its just _.math.sqrt(x) in Python Scripts: import math math.sqrt(x) Regards Tino
