Purchasing gift vouchers of any value

[kama_k]

Hi,

I have ms2-max 1.5 installed and its working lovely, the only thing I can't find is a way to let the customer specify the amount they would like to pay for something, for example a gift voucher for £10 or for £150, without giving loads of attributes, I thought of letting them specify an amount of £5 vouchers to buy, but I can see the customers getting confused with that. Any pointers would be much appreciated, the idea is they can buy vouchers for family or friends and can spend as much as they want.

Thanks
