crystal reports extracting a single field from data source

Question

I am using SAP Crystal Reports 2016 Support Pack 4. This sounds really simple but I am finding it to be a bit challenging.

There is a report that I created that iterates of several columns. What I am looking for is a way to extract one particular field from the table of data and display it in the report

For example, I want extract the 400 which is Column2,val4 data field and place it in the report. Column 1 Column2
val1 100
val2 200
val3 300
val4 400
val5 500

How does one do this?
