Problem with width tool(mac)

[Anna35136054rlw0]

Hi, 

whenever I click with width tool I see this icon(circle with the line). I can't also change "variable width profile". My path is selected and layer is unclocked. 
When I go to the other document I don"t have that problem so it's just a issue with this document. 
Please Help

THat is a live paint group. In a live paint group you cannot have width profiles applied. Do you need the live paint? If not, expand it.

You are editing a Live Paint group, width profiles are not supported in Live Paint.
