Row_Updating server event ($rsnew)

[elonmusk]

I have row updating function in many page, it is working there, but in one page alone when i pass the parameter in $rsnew, the following error is showing, Undefined array key.

As the error said, the key you used did not exist in $rsnew. You may view and check the content first by, e.g. die(var_export($rsnew));.
