I pasted the following in the transformation script window:
sub main()
{
  if ($1 == 0)
     return 1;
  else
     return ($1 * 2);
}
When I click the test button I get the following: request failed 'Incompatible operation'

Can I not use the test button?

Why does this fail in transformation script:

if ($1 == null)
   return 0;
else
   return ($1 * 2);
