Hi,
It looks like you just have a minor typo in your code. The second
*Predicate* is named *predicateAdGroup*, but you set the attributes of the
*first* *Predicate* named *predicate* in the second section.
Predicate predicateAdGroup = new Predicate();
predicate.field = "AdGroupId";
predicate.@operator = PredicateOperator.IN;
predicate.values = new string[] { adGroup.id.ToString() };
If you change that section of code to the following, then your example
should work as expected.
Predicate predicateAdGroup = new Predicate();
predicateAdGroup.field = "AdGroupId";
predicateAdGroup.@operator = PredicateOperator.IN;
predicateAdGroup.values = new string[] { adGroup.id.ToString() };
Thanks,
Josh, AdWords API Team
