In Finale, polychords (one chord over another) are written as stacked, rather than slashed or side-by-side. If you do a Google search, you will find a number of comments on how to do it.

Thank you for answer!

My english level is so low so it's so hard for me to write correct meaning phrase for google at this case.

Im writing polychords as well but Finale doing auto correction and clearing "7".

I need to write this Chord

Watch this YouTube. It's exactly what you want!

I have not problem with writing polychords. I just have a one problem - when i witing 7 chord finale ignoring this 7 and writing just simply chord.

I think i found my problem in other post:

Isn't this what you want?

Yes MIKE this is what i need! but finale ignoring that 7! How you did this?

I entered the E7, hit the up arrow, entered the line as shown in the YouTube video, hit the up arrow again, and entered the Eb.

I had to move the line down a bit, but that was all.

This is so hard work but its works. Thank you Mike I hope Developers will add some more easy way to do this.
