error importing

I’m trying to bring a model i made into my current project. i was told to use shift f1, but i keep getting an error measage. it says wrong indicated name. so now what do i do? can someone help me out?

When you append (( shift f1 ) also under file append) is it a blend file ? If not you may need to import. If so did you click object or something then select whatever . It should work . using a pin sometimes you need to give it a good tap . in 2.5 it need to turn orange ( the selection ) ( was my biggest problem)

I did pick object and it is a blender file but it’s not working.
