Why is the number 2 displayed?

Hydrowizard, we all have those moments. I know I have.

What, even in the line of code I quote above? You can't see a "2" in that?

Let's stipulate that you've noted everyone else's advice and recoded that
to be valid:

#fnTest(1,2)#

You are passing "2" as the second argument into a function, which you've
instructed to be called "arg2". Then you output the value of "arg2". How
is it a mystery to you that when you set a variable to have a value of "2"
that when you output it, a "2" appears?

Because it comes after the first comma.

why is the second argument value 2? Where is that defined?

<CFOUTPUT>#fnTest[1,2]#

is this how you call the function? why are those square brackets instead
of ( and )? where's the closing </CFOUTPUT>?

anyways, those look like a 1 and a 2 to me, but maybe not everyone can
see a 2 for a 2...

This line, #fntest[1,2]# called the function and the value of the 2nd argument is 2.
I didn't realize you could call a function with square brackets though.

Loosely typed language.

This is not an issue with the stateless nature of HTTP requests and
responses, but rather that CFML is loosely typed and does not enforce
the typing of variables.

[] Square brackets are for arrays.

() Parentheses are for parameters for a function.

Change that to: #fnTest(1,2)#

Unfortunately you just ran into a peril of a stateless language.

ColdFusion happily let you redefine the variable 'fnTest' from a
function to a two element, one dimension array without a bit of notice
or complaint.
