Hello, y'all!

I'm a beginner when it comes to coding. For my job I got a task which I have to do over 400 times. I thought: hey let's write a macro for it. So I did, and it works fine for 'Parts'. And yes like you can already guess, it doesn't work on assemblies. I've tried a lot but without any luck, unfortunately. Underneath I will explain how my macro works:

1. I have opened a part or assembly;
2. It will look if there is a drawing;
   1. If not, it will end the macro.
   2. If there is a drawing the macro will open it.
3. When we opened the drawing it will go back to the referenced file (part or drawing) of the drawing (This is where my macro stops working for the 'Assembly' extensions, for 'parts' it works already perfectly)
   1. I can't figure out why it works with parts but doesn't work with assemblies
4. It will execute a 'save as' function (with dialogue box)
5. It will save it as the new name and it will open the drawing again
6. Then it will save the drawing through a 'save as' function (again with a dialogue box)
   1. Maybe someone knows how I can use my entered filename from step 4. to save with this name the drawing as well. Would be awesome!
7. It will close the drawing.

Can someone help me with this problems (Bold black letters)?  I would really appreciate it! Thanks in advance!
