I have a question which is probably easy to answer, but cos I'm new to
JSP I don't know how to do it myself:
Is there any way to pass a value from a selected row straight back in to
Java? What I'm trying to do is take a load of selected values and add them together to form a total. This is basicsally what I'm trying:
<%
int subtotal = 0;
subtotal += <jbo:ShowValue datasource="paygroup1" dataitem="MY_TOTAL" ></jbo:ShowValue>;
%>
But it gives me an error when I try to do it like this.
I'm sure I've done something like this before when I used JSP a few years back, but I can't remember what.
Any help is much appreciated!
