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.
