Hi,
Congratulations about your excelent script!

I am working on it and I would like to know how can script block adding an entry already existing in database.

For example:
dbase=(id,productname,code,price)
(1,Fanta,2154,2)
(2,Coke,2155,3)
(3,7up,2156,3)

Now, when on adding:
Name: Icetea
Code: 2156
Price: 3
>> SUBMIT

I need to block this entry because code 2156 already exists in dbase, the code correct would be 2157.

I want to make an adaptation to block all equals entries on code field

Thank you very much,
