How variable auto populate works on onchange client script

[Are Kaveri]

There is variable abc which auto populate based on xyz variable value.

I have abc value used in another validation . Since auto populate works after onchange the abc value is ideally getting zero. 

how to get through this issue ??

first value of abc need to populate and after that my validation should work.

@Are Kaveri Could you post your client script here. Also, try auto populating on onLoad script instead of an onChange script.
