removing a line from a text document

[Kevin]

ok ty yeah once i removed the flag it works without deleting but i have 2 get the line count cause the entry could be on any line. maybe line 5 our could be line 25 u never know.so i just made it count the line so i had the line number 2 delete.Cause it won't let me use anything but a number or an integer in this line
a.RemoveLineN(x)<-----x being an integer
