Using True/False in a Variable File Upload using Excel and a VB field script

 
If you type "True" into an Excel cell, without a leading quote mark, the value stored there is not the string "True."  It is a boolean value equal to true.  If the field in the variable data file is then being used in a VB field script, the value will not be read correctly.  You will need to choose a different value for true/false - such as 1/2.
