My Javascript seems to work, but doesn’t return any value other than 0. Here’s the details:

In my survey I want to show respondents the future cost of their child’s college based on an official estimate. To do that, I ask two questions:
1) What college type you hope your eldest child will attend - here they can select 1 of 3 options
2) In how many years will your child start college - this is a text entry that only allows numeric values

I created an embedded data at the very top of the survey flow, called “CollegeCost” and set value to 0. 

I have a csv file saved on an external drive with no access restrictions. In question 2 above I added the following JavaScript. I made sure the names of the csv columns are correct as well as the case-sensitive wording of the answer options. 

In the next survey page I then include the following piped text: ${e://Field/CollegeCost}. This value is always 0 no matter the values I put in the two questions. 

What am I doing wrong?
