Hi

I’m reading an xls file using Microsoft Excel Input step and Modified Java Script Value step for transforming strings and dates

I see the following error when I try to get the declared variables (Get variable button):  
Modified Java Script Value.0 - ReferenceError: “field” is not defined. (script#3)

js code:  
var test = field\_Date;  
var test2 = field\_str;  
var test = field\_int;

Fields with numerical values are obtained without problems.  
Fields are being displayed under Input Fields.

Thanks

The problem was in the names of some that had the same prefix. I changed the name of the columns and it worked.

Name before:  
abcName  
abcDate  
abcCode

Changed to:  
Name  
Date  
Code
