Run List Index was outside the bounds of the array. Error

[ek3ekytop]

In my template I asign value 0 to a variable then load profile and when load profile there no number (0) asigned to this variable and in log I get error [Run List Index was outside the bounds of the array.]
Can someone explain me what is the problem ?

Problem solved! Created new variable and no problem after that but is strange at all!

What was this variable? your own or some environment variable?

It was my own variable. In this project I replaced old login form with load profile instead login each time ... then I get this error to 1 of my variables ... Problem solved when I created other variable .
