I am trying to call a function upon a change to a field in my
to update fields successfuly but in this case, I need to read a
database to get a item on-hand balance and then display it in the
form. I don't know how to do a database read in java so I thought I
would write a standard function.
So, in the item selection field on my form, I have onchange
"get_bal(beg_bal,end_bal)". when a user selects an item, I want it
to go out, read the database for that item and update the form with
the current balance. I get an error when I call the function,
regardless of what command I ahve. What am I doing wrong? Is this
the wrong approach? Code attached. Thanks in advance.
