Is anyone up to a challenge?

The program has this error:

Code:
Run-time error '13'
Type mismatch


It crashes at a line of code that is supposed to be calling a funciton in the C++ DLL.
The line of code is this:

Code:
ErrorStatus& = atxml_ValidateRequirements(XmlBuf, "PawsAllocation.xml", Response, 4096)


Now, let me tell you what everything is defined as:

Code:
Global ErrorStatus As Long

Code:
Global XmlBuf As String * 4096

Code:
Dim Response As String
Code:
Declare Function atxml_ValidateRequirements Lib "AtXmlApi_Dbg.dll" (ByVal resourceName$, ByVal IDQuery%, ByVal resetDevice%, instrumentHandle&) As Long


And in the C++ program:
Code:
extern "C" ATXML_FNC int atxml_ValidateRequirements(ATXML_ATML_Snippet* TestRequirements, ATXML_XML_Filename* Allocation, ATXML_XML_String* Availability, int BufferSize);
