sub vi works alone but not in main vi

[looser]

Hi All..
If u have a look at the attached vi u see that there is a sub vi ,called Ramping machine, which is kind of numeric machine producing current values for writing process (set kepco vi.). My problem is that ramping machine sub vi is working properly individually, but when i insert it in to the main vi. it s not working any more. I couldnt find out the problem. can u have a look and have an idea?
thanks

This is just a guess,

I am not sure why you have so many sequence structures?

You may want to try and step through the code to see where the error is. You could also "right click" on the Ramping icon and set the properties to open when called and run the program.

Hope this helps!
