Regression returns Linest() error

Regression keeps returning Linest error. All values are numbers (although I've tried as general as well). What's the deal? Thanks in advance!

X Y (I cant get Y to line up. the left column is an x variable and the right column is my y variable)

Ultimately, I got this to work by copy/pasting my dataset into a new workbook and then simply running the regression from there!
I don't recall what my results were, they were not found to be statistically significant so I deleted the regression and moved on with my analysis.

Thanks anyway!
