Write Table to Excel

Question

I have taken the write table to xl.vi example and modified it so that I can use it. Write now I have a vi setup that displays certain columns of data that I am pulling from a txt file in both a graph and a table. Then I am trying to write this table to xl by following the example, however I get the error 97 when running the vi, and a blank excel workbook opens up. I think this has something to do with how the table I have created is used to try and enter this into excel. Any help you can provide would be greatly appreciated. Thanks.

Answer 1

Error 97 is "LabVIEW: Null Refnum was passed in as input."
You might wanna check whether the Automation Refnum is linked to the correct ActiveX class in the "Open Excel" VI.
In your diagram, as Dennis pointed out, it has no dataflow. The row header and column header in your table are both empty as well. That results in three for-loops doing nothing. Wire your "Hour" variable directly to the input of the third loop instead. Also at the end of the program, you should close all opened references regardless of the "Completion Task". Put only the invoke node "application quit" in the case structure should do.
Hope this helps.
