    Hi Zack,

    There is no way to do this type of operation in BA itself. You would need to use a plugin in order to achieve this.

    Please see below for further details on plugin:

    Hi,

    Thanks for the answer. As I´m not familiar with scripts and in a hurry - can anyone pls provide/show me how the source code (script itself) for this simple plugin would look like ?  I know how to use variables and attach plugins. Would be very grateful :)

    I believe this was answered via support, but not sure. This example takes a plugin command updatevar!firstvariable!secondvariable.

     

    The plugin then adds the two together, and puts the value in firstvariable.

    Yes, it was solved by support, Thank You!

    In the script above right parenthesis   ")"  are missing in line 109 and 110.

    For some reason this isn't working in my project (BrightAuthor 4.6.0.35)

    - I added the plugin via autorun
    - added two variables, even named them firstvariable and secondvariable (access: shared, type:local)
    - firstvariable has value 10
    - secondvariable has value 20
    - added a live text element with: uservariable 'firstvariable'
    - create a touchevent on the entire screen (remian on current state), and added (under advanced) a 'send' command -> send plugin message -> updatevar -> updatevar!firstvariable!secondvariable

    When I preview the presentation the text shows the value of firstvariable -> 10 nothing happens when I click the screen.

    Obviously I am doing something wrong, any advice?
