[Zope] 3RD REQUEST: PLEASE HELP

[Eron Lloyd]

Ben,

Off the top of my head it seems you are mixing data, logic, and presentation 
unnecessarily. Is what you're trying to accomplish the generation of a style 
sheet value for a font? This to me seems wholly complicated... just browsing 
the code makes me think your error is coming from the "_.int(subtotal)*.05)" 
in the variable assignment. Thats why the exception

Error Type: ValueError
Error Value: invalid literal for int(): 126.0

is raised. You may want to keep "shipping" a float and only coerce it into an 
integer when necessary. That could help.

Perhaps if you explain what you'd ultimately like to do we could find an 
alternate and more simplified way of approaching it.

HTH,

Eron
