If I create two new COM objects

  $first = new COM (object1.function);
  $second = new COM (object2.function);

then 

  $a_var = $second->task;

  $first->dosomething($a_var);

I get the following message -

Warning: Invoke() failed: Type mismatch. in D:\Data\docs\whorl_test\connect2.php on line..

the rest of the script I'm running seems fine, it only stops working when I get to this line. The data being passed as $a_var is in the form of an array.

Thanks for your time,

John.
