Interchange automaticaly formats [subtotal] as a currency.  You'll need
to get rid of the fomating before you can check it's value. 

Example: assume subtotal contains 5.00

[subtotal] prints $5.00
[subtotal noformat=1] prints 5.00

One (of many) ways to check the value is....

[if base=name term="[subtotal noformat=1]" op="!=" compare="0"]
  It's not equal to 0
[else]
  It is equal to 0
[/else]
[/if]

Onother way might be to set a scratch variable and check that.

[tmp some_var][subtotal noformat=1][/tmp]

[if scratch some_var != 0]
  It's not equal to 0
[else]
  It is equal to 0
[/else]
[/if]
