Whenever I try this when they're the same type it works.

It they're not the same type it'll never work. Unfortunately the type() 
built-in isn't available in DTML or Python scripts (if you go to an 
ExternalMethod you should be able to use it.)

What you can try is this:

str(i)==str(j) to compare the string representations

or, if you're dealing with a certain type of number,

int(i)==int(j)
float(i)==float(j)

In DTML, you have to call these from the namespace '_' (underscore) as so:

_.str(i)==_.str(j)
