As a librarian who will be setting up mapping profile, I want to set the value of the transformation so that when the record is exported using my mapping profile it will contain the fields and values that I configure.
Given: the field names are populated
When: the user starts typing in Transformation textbox
1. Checkbox associated with this field is selected
2. The label with the number of selected records is updated
3. The field may contain alphanumeric characters and will contain 3 digit field name, white spaces or two digits for indicators, a subfield delimiter ($) and the subfield identifier (alphanumeric)
