Make sure that your csv file has a column for each required test field (these are indicated on the test edit page with a red asterisk). The error is telling you that you don't have Status. The easiest thing to do is make your column heading the same name as the name in the test (for example, "Title", "Status") . Make sure that you include a column for Folder Name. Otherwise your tests will be added at the root level and you don't want that. You can also use the mapping page (you attached a screen shot of this), to tell the system where you want the csv file column to go. I have done this a lot, so please let me know if this doesn't make sense.
