I am an user of ArcGIS(Arcmap) but I do not know much about programming. I have been given a python script and it basically combine two fields and put them in a new attribute field e.g. attribute field 1 = 000 and attribute field 2 = 1, scripts makes attribute field 3 = 0001. After I assembled a new workstation, I installed ArcGIS 10.6.1 and this screenshot below is what occurs when I try to run the script. I am positive that the script is good because all of my colleagues run it without problems. I have even tried reinstalling Windows 10 as well as many other things such as reinstalling ArcGIS. I am kinda running out of options... and I don't know what to do.
If anyone has any suggestions, please let me know, I would really really really appreciate it!
