'Bind skin' doesn't work, help please

Hello, I was trying to do rig for the first time and when I got all my joints done and hit the bind skin button the syntax error pops up. I tried restart maya in deafualt, dele history, re-do the joints but nothing seems to work help please. I have no idea what I'm doing wrong. (excuse my bad english please )

Once check your smooth bind option !

I'm not sure what you mean
Btw. here's the settingsUploading...

I somehow fixed it. No idea how

once you click on bind skin,
It will not give you accurate result it will give you rough skin paint...
You must do manually to get accurate form.

Click on mesh>shit+right chick>paint skin wedges>

You can paint your mesh custom
