CampaignSharedSetService is not working

[bsoft.b...@gmail.com]

Hi,

I created a shared set on the MCC account and now trying to assign this set to campaigns under the mcc accounts.

I used the example -https://developers.google.com/adwords/api/docs/samples/csharp/advanced-operations#create-and-attach-a-shared-keyword-set

and it is not working for me - the Error I get is that the campaign id is not valid (what is not true).

I think it's related to the AdwordsUser object that I sent but I couldn't solve it...

What should I do ?
