Hi Nagarjuna,

You dont need a trigger for this. If you create a validation rule on Objx

Objx.Num1 > Objx.ObjY.Num2

Where Objy is the parent object and Objx is the child object and you can create this rule on the Objx. So whenever the value of Num1 is greater than Num2 whether you create a new ObjY record and associate to the Objx record or update Num1 on Objx or Num2 on Objy, will fire.
