Why is it so hard to capture timings and write them out line by line into a notepad file in a .NET script? Seems so simple but I cannot find an answer.

I have a spreadsheet.

This spreadsheet contains the values that get input into our formulas on the website.

Spreadsheet contains expected values.

Website contains actual values.

I want Silk Test to input the values from a spreadsheet, capture the output from the website, and then write it to a notepad comma delimited file line by line with each line representing each step.

ActiveData can pull from a spreadsheet.  Do I need to setup a notepad active data and write to that?  Why is this so complicated?  I can't use a visual test for this, so please, .NET script help is much appreciated.
