Preventing payment

Hi,

I want to be able to prevent a person from paying when PAY option is displayed with money event, but allow for others as necessary. So basically do something that doesn't allow the person to pay once they click 'PAY' or disable pay for that person.

Reason I want this, is so that number of items I can sell is limited to a certain amount per day for each avatar.

However, I cannot see how this is possible with functions available. Can someone let me know if this can be done and by using what method. I would know when they have reached their limit, but need to know how to prevent them from paying and buying.

Thanks in advance

Just have it detect that the person can buy now more, then if they pay, it gives an error message, doesn't give them the item, and pays their money back.

ah thanks...so simple a solution i missed it.
