Summary:
After configuring and running my Citect project, on the Trend Page, the copy to file or clipboard will not output values. The print trend generates a hardware error, such as "Invalid Argument". No data is sent to the printer.  

Solution:
The Trend Type may be invalid. This may be set to "0" if you used Excel to edit the database. Check the Trend Tag form and choose the correct trend type from the drop down box.
