Hi , i’m trying to use the run script function with an argument that as a custom properties. it’s not working i’m missing something but don’t know what.

**here is the script**  
runScript(“shared.backgroundcolor.backgroundcolor”, 0, tag("[Master\_par\_Tags]Batching/A220/AGT SPT/AGT"+{Root Container.monIndex}+“_PLC/SPT\_1_”))

I try also like this  
runScript(“shared.backgroundcolor.backgroundcolor”, 0, (tag("[Master\_par\_Tags]Batching/A220/AGT SPT/AGT"+{Root Container.monIndex}+“_PLC/SPT\_1_”)))

Please note that {Root Container.monIndex} is binded with the value of a slider.

Thanks
