I think eblog gave you the correct answer, but it needed more explanation as follows:
You must do the following command to get your correct output.
Your wrong command : reg lny edu oj oj2 ft ft2 s level(99%)
My suggestion : reg lny edu oj oj2 ft ft2 s,level(99)
I will point out your method of using "level" option of regression command which can be explained in this Stata.com site :

The default level is 95. So you must change and just set the level from 95 to 99 in the option after the ",", not 99%.
I hope you take a good solution.
