How are you acquiring the data and what type of data are you passing to the Write LabVIEW Measurement File? Channel names in a dynamic data type are automatically written. If you don't have dynamic data, then it's probably a lot easier to use Write to Text File for the column headers and Write to Spreadsheet File for the data.
Even if you get this to work, that's not even close to the same thing as writing to Access. The LabVIEW Measurement File is a text file and you would then have to open Access and import it. To write directly to Access, you can purchase the Database Connectivity Toolkit. If you are comfortable with SQL, then there is a free toolkit called LabSQL<>.
And please, in the future, use something meaningful in the message subject. I have no idea what 'dweiland' means but it certainly doesn't apply to your question.
