Dynamic stamp with dropdown for accounts and todays date

Hello:

I am brand new to this.................. I'm trying to develop a script for a dynamic stamp that will create a popup dropdown list of accounts to be inserted into the "Account" field of my dynamic stamp, along with also populating the "Date" field with the current date. Could anyone help me with this? If someone could post script that just says something like "Account 1" "Account 2" etc., I can change the account names myself. Thanks so much! Below is what I have so far, but it only gives a blank "Account" popup. I have no idea how to make a dropdown list. I have also attached my template. Thanks again!

{

this.getField("Account").value=app.response("Account:");

this.getField("Date").value=util.printd("mm/dd/yyyy",new Date());

}
