Hello all!

I’m trying to loop through this to when the Command\_commands shows ‘G4N3F’, I need to write to BP2\_Has\_Cook.

if Has\_Command \< 1:  
system.tag.write(“AGCs/AGC2/To\_Cart/Command\_commands”, ‘DG4N3F’)  
system.tag.write(“AGCs/AGC2/To\_Cart/Command\_distances”, ‘113,14,127,157’)  
system.tag.write(“AGCs/AGC2/To\_Cart/Command\_rfids”, rfid\_35+","+rfid\_36+","+rfid\_30+","+rfid\_8)  
system.tag.write(“AGCs/AGC2/Status/JustLoaded”, 0)  
system.tag.write(“Backpacks/BP2\_Has\_Cook”, 1)  
else:  
pass

Thank you!
