how to read data from txt file respectively

[crossrulz]

Ok, here are some tweaks.

1. Use Read from Spreadsheet File to get your values.  It is a little cleaner.
2. Do not keep opening a file inside of the loop.  Open it once before the loop and close it once after the loop.  You can then read/write to it as much as you want inside of the loop.
3. I really like to use Format Into String to put my values into the desired format to write to a file.
