Assign values to radio button fields and add them up (when turned on).

I do not need to store the results of my calculation. Using the code field works.

What I mean by using a variable is instead of

return (int) '[cb_field1]' * 2;

Can I have

return (int) '[cb_field1]' * variable1;

where variable1 = 2 somewhere.

If you mean variable1 is another field then you'd just substitute in that other field. Otherwise I've no idea where you plan to store that variable. You've full access to PHP so you can use PHP variables, make an SQL query, or whatever you like using PHP.

You are right. variable1 can be an integer field that I use in my calculations.

Thanks

Maybe last question on this topic: Want to break up command to different lines:

return (int) '[cb_field1]'
+ (int) '[cb_field2]'
+ (int) '[cb_field3]';

You can break it up into new lines if you want. Just be sure to have Joomla debug mode and maximum error reporting enabled so you can debug your code in the event of an error occurring.

1. Just wasn't sure I needed special line break characters with multiple lines.

2. What is the formula for adding the results of two code field values.
