script-fu multiplication : not enought argument

Question

simple multiplication is failling in my script-fu. the folowing code

    (print "hello")
    (print (/ 4 3))
    (print (* 3 4))
    (print "world")

Gives :

     "hello"  
     1,333333333.0  
     Error: ( : 1) not enough arguments

Any idea ?

I ran into a similar problem when trying to add new functionality to someone else's script. I wanted to provide my solution in case anyone else runs into a similar issue.

In this case, there was a '(let* (...))' statement that was being used to initialize some variables. The original author of the script wrote '(let * (...))' - with a space between let and star - which means every vector in the 'let' statement becomes the expected arguments for the '*' statement.

Please excuse (and correct if necessary) any incorrect nomenclature regarding Scheme. I have barely just been exposed to it.
