How do I determine the budget?

I want to fix it in X U$

[silverbytes]

Hello I dont see where to put how much I want to spend.
I put the minimum and max.. but is there any instance where I say "show until my X U$ runs out?"

must I manually cancel the account later?

Are you talking about an instance where you only want to spend $x dollars and then stop running the ads, or only spend $x per month?

spend a fixed amount of dollars no matter how long it takes. Dont wanna pay more than my assigned budget.

I already put a quantity for each day maximum... but along time that could be millons of dollars if I can't determine when stop discounting of my account...

Where do you set that.

I've recibed an email to activate the account but I'd like to be sure first...

There is no way to define a max spend amount.

The closest you can come is set a daily budget, and then set a campaign end date based on how long it takes your daily budget to meet your total budget expenditures.

When it gets close to the campaign end date, you can check your budget, and then extend the campaign if you won't meet your total spend by then.
