Are you working with DTML and ZClasses? If so, It could be that a
variable on a dtml method is being adquired from a ZClass or from other 
place. I had some similar problem and solve it just like you, renaming
the variable . If I'm not wrong, a way to avoid this is restricting the
name space on a dtml-with tag:

<dtml-with blah only>
   do something
</dtml-with>

If you use python products and ZPT, you will hardly have this problem
because you have to specify the object that contains the variable.
That's a reason why people here recommends not to use dtml: you have to
be careful about the name scope of your variables
