Trouble exporting data from Delta V to Excel

Hi I am a student working on a project and would be grateful for any advice . Using an action block and counter  I have sampled 10 values for flow rate across the range of a control valve in 10% increments . The values for flow rate and % stem position are written to internal write parameters. I would like to export the data to excel where i could plot a graph of valve stem position vs flow rate. The Excel add on is installed. Thanks
