you must use TAG0 instead TAG
if you use TAG (without 0) the script will return a empty text if the tag is not set. Using TAG0 it will return 0 to prevent the blank result

just translate the script and you will note the difference

example: if the TAG.A is not set, sphere will read the script line as it is:

IF (==1)

this will result a error because sphere doesnt know what is this empty string. If you use TAG0 it will return this

IF (0==1)

and this will work fine because sphere can read this line without problems
