Folks,

I am still learning functions ... I wanted to create something like:

#declare foo = function(a,b,c) {
   #if (a>0.0)
      #declare a=a+1;
   #end
a+b+c
}

My problem seems to be that the formal parameters supplied to the function 
don't seem to be in scope for the expressions.  It is as thought they were 
not declared.  When I try and run this, I get:

-----

File: C:\Documents and Settings\kolban\My Documents\My 
3D\Projects\Tiles\test.inc  Line: 2
#declare foo = function(a,b,c) {

#if (a <----ERROR

Parse Error: Expected 'numeric expression', undeclared identifier 'a' found 
instead

Returned from renderer with error status

-----

Am I not allowed to use function parameters in the conditionals within my 
function body?

Neil
