Graham, thanks a lot. You are right, of course, and I was blind. Now it works. 
But - I'm still having problems with this function. If I apply it to the 
following formula:

#include <ParamOptimize.afl>

P = ParamField("Price field",-1);

Periods = popt("Periods", 15, 2, 200, 1 );

Hull=DEMA( 2*DEMA(p,int(periods/2))- DEMA(p,periods),int(sqrt(periods)));

Plot( Hull, _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), 
ParamStyle("Style") );


space = Param("Graph Space", 10, 0, 25, 1);
GraphXSpace = space;


... I get the error message mentioned - even if I replace popt with Param! The 
#include line alone is enough to cause that error. Isn't that strange?

Greetings, Thomas
