NA in data analysis

I am using the analyze section of the edit experiment so that I can create the data files which have mean, median, etc. This is what my data looks like:
2 757 1

2 1031 1

2 610 1

2 726 1

2 684 1

2 978 1

2 642 1

2 566 1

2 608 1

1

"HT83"

There are no conditions, and I honestly don't really care about correct or incorrect, just the reaction time. But when I put in the RT data is in column 2, I always get NAs back. I still get NAs if I include the status (which again is not important in my analysis). Is it to do with the blank spaces? Is there something I am missing? 

Thanks!
