[RESOLVED] Problem when passing UDTs to subs

[krtxmrtz]

In a module I have the following declarations:

Public Type MyUDT
   X As Single
   Y() As Single
End Type
'
Public MyUDTInstance() As MyUDT

In a different module:

Sub MySub(DummyVarName)
'...
' Some operations are performed here
'with the quantities:
'DummyVarName(SomeIndex).X
'and
'DummyVarName(SomeIndex).Y(SomeOtherIndex)
'...
End Sub

Finally, in a form there's the calling statement:

Call MySub(MyUDTInstance)

Of course, MyUDTInstance and MyUDTInstance(SomeIndex).Y(SomeOtherIndex) have been previously ReDimensioned and given values.

Now, when the sub is called I get the error you can see in the attached picture which can be translated into English more or less as follows:

"Compiler error.

Only those user defined types from public obejct modules can be passed to functions linked at run time or forced to or from a variant"

Anyone knows the reason?
