silly question about promo codes

Hi All,
Please forgive me this very silly question..

But, I cannot see where to enter the promo code when i sign up for a yahoo search marketing account..

I just assumed it would get automatically credited to my account. But, after i have uploaded the minimum deposit my balance is still the same.

Are you supposed to enter the code somewhere?

Any assistance would be greatly appreciated!

 

thanks, i found the section that says it takes up to 72hours for the credits to show..

 

also you can email support and give link from you signed and they will credit amount in 48-72 hours.
