Tag path dynamic

Hi,

I create dynamic tagpath. In my tag they need addition 2 number (such as [~]MachineFolder/Machine_3/HighSP),[~]MachineFolder/Machine_4/HighSP……

In value :
[~]MachineFolder/Machine_{Root Container.machine::MaNum}"+"{Root Container.machine::const}/HighSP

Is it right?

Thanks

Modify as below: Tag(‘MachineFolder/Machine_’+{Root Container.machine::MaNum})+tag({Root Container.machine::const}+’/HighSP’)
Write this under expression field.
