does the withdraw function in the script at Bitvest also work with Litecoin?

withdraw(amount,bitcoinaddress) Returns: void. Parameters: 1: Amount to withdraw, double. 2: Address to withdraw to, string. Withdraws the specified amount to the specified address if the site supports it.

Yes. Withdraw function can work with anycoin. I'm not sure if it is possible now because of the 4 digit pin security update.
