reference textbox value

I have an excel data source with multiple tables in different formats. The table I need to display has 2 columns that references cells in the excel data source. How do I do something like this? The 1st column is a description. The 2nd column is the total. :crazy:NewStudents [color="red"](excelDataSource[A20] + excelDataSource[A25])[/color]Faculty [color="red"]excelDataSource[D18][/color]Alumni [color="red"]excelDataSource[E25][/color]Sponsors [color="red"]excelDataSource[C45][/color]
