CF Param is working as it's supposed to. CFPARAM encapsulates the follow
ing
logic:
Your first cfparam does this....
IF ( NOT IsDefined('foo') ) { foo = bar; }
Your second one does this.....
IF ( NOT IsDefined('foo') ) { foo = boo; }
The first one executes and defines foo and assigns it the value "bar".
The second IF does trigger because Foo IS defined. You use cfparam to
either predifine a varialble to avoid a page error (as in when you are
populating form
fields with their own submitted values) and/or to set a default value in
the
case where
a variable has not yet been assigned.

Subject: CFPARAM Question
Do subsequent CFPARAMS of the same variable overwrite each other? I
thought so, but they don't seem to.
<CFPARAM NAME="foo" DEFAULT="bar">
. later ...
<CFPARAM NAME="foo" DEFAULT="boo">
If I check for foo it's still "bar" instead of "boo"...
Is there a way to duplicate my intended behavior another way?
