Calling xlsm functions from xlam

[EdH42]

Hi

Long time lurker finally signed up as I can't figure this out.

Test.xlam:
contains a class TestIF (Test interface) -- PublicNotCreatable
contains a function RunTests (starts execution--called from a menu) which is supposed to callback to the xlsm file to instantiate the class that implements TestIF

Test.xlsm:
contains the class that implements TestIF.

When creating the code that instantiates a class that implements TestIF in the xlsm, intellisense knows what a TestIF is.

So far, so good, but I'm trying to run things backwards, essentially trying to call a function in the xlsm file from a function in the xlam file. The menu selection calls RunTests just fine, but when RunTests tries to instantiate the class to be tested, it complains about the variable or user-defined type not being defined. when called as "New TestClass" it complains about the user-defined type and when called as a public function "CreateTestClass" that would return the newly instantiated TestClass located in a module in the xlsm file, it complains about the variable not being defined.

While I can think of a few workarounds that involve moving the test function definitions into the xlsm file, I'm hoping there's a way to do things this way as wrapping everything into the TestIF class seems the cleanest way to go about it.

Any ideas???

Thanks
