In SC 4.99, the field Custom Textbox #1 is limited to 50 characters. This is because the table Smith_Customer,  UDTB1 is a varchar(50).

The is too short for a meaningful message.

I would like to propose changing it to varchar(500), making this consistent with the special instructions field length.

I have tried this on a test portal and it seems to work fine. This would be a very simple change, but of course you would need to check your code behind and stored procs that it doesn't break anything.
