Write data to measurement file - column headings

Hi

I am having an issue with the write to measurement file.vi

When I use the DAQassistant data output as the data source, it works exactly as I want - column headers, time stamps, correct sample rate etc

However, if I connect my array (I'm certain that's not the correct way to do this), I only get 2 columns - one with timestamp, and one with one single reading from each indicator.

What would be the best way to 1) take the output from each indicator into a separate column, and 2) sample this data at a specified rate, continuously until I hit stop?

Thanks
