Problems encountered using query and queryTask

I have been working on a simple query for a map service I have running. The problem is on the first query of every seesion I get the following error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

But when I tell it to "Dismiss All" it returns what I am looking for and from then on all queries seem to be working fine. I have attached the code to this post. the one thing I have noticed when I debug it is that the "where" value is null even though there is a value there.

Thanks
Any Help would be greatly appriciated

Error is on line 32
var mp:Multipoint = new Multipoint([],myGraphic.geometry.spatialReference);
the variable mp is not being used in rest of the code. Runtime error will not be thrown if this line is commented out.
