    Hey this should not be tough:
    CFSET - this tag will overwrite a variable to the value specified
    CFPARAM - if the variable specified already exists then leave it alone otherwise it creates and set it to the value of the DEFAULT parameter.

    If the explanations provided are "not good enough", they should just read the documentation.

    You've been reading "How to Win Friends and Influence People", I see.

    You could - of course - just go read the docs. They're fairly explicit on
    what each does:

    <cfset>

    <cfparam>
    http://livedocs.adobe.com/coldfusion/8/Tags_p-q_01.html

    CFSearching (you people sure do have weird names) gave you a good start,
    and explaining how 90% of people probably utilise the differences between
    <cfset> and <cfparam>.

    I have never read your bio. But your dry wit makes one suspect you are British. (No that is not an insult. I just enjoy a dry sense of humor ;-)

    There are several differences.

    Loosely put, the primary difference is that cfparam sets the value of a variable _only_ if that variable does not exist. Whereas cfset always sets the value of a variable. ie If the variable exists, it overwrites the existing value. If it does not exist, it creates one.

    But again, there are several differences. That is only one.
