   Hello,

   Nice calculations:)

   Help me understand what your question is about, so please answer these:

   • are you asking how to use robotlegs to communicate the results of a calculation to another class in your app (to a Model or another mediated View..)?

   • or are you just asking how to add multiple results to your "TareaDisplay" inside your Calculator view?

   By the way, the code you're having inside the mediator belongs to the view. The Mediator is not meant to be used as code behind.

   If I understand correctly, you're looking for something like this:

   http://en.wikipedia.org/wiki/Shunting-yard_algorithm

   here an as3 implementation:

   http://code.google.com/p/filthmunster/source/browse/fm-utils/src/ma...

   BODMAS rule is definitely out of the scope of this forum, so for further questions on the matter you should try other forums, like stackoverflow , math.stackexchange, or search the web for the source code of scientific calculators written in different languages - the algorithms being the same.

   Cheers,
   Ondina

   Hi Subrat,

   I'm sorry, but I cannot help you.

   Obviously, you did not understand what I said in my first post :)

   This forum is dedicated to questions related to the robotlegs-framework.

   Your problem is not a robotlegs one.

   You should try asking your questions on these sites:

   http://stackexchange.com/sites# - here is a list of all the sites available

   http://stackoverflow.com/ - here, you may want to tag your question as 'as3' and 'math'

   http://mathoverflow.net/

   Good luck:)
   Ondina

    hii Ondina D.F.

    first of all thank you very much for your response.
    i have completed that module.

    Now i want do do a weather forecast app in flex using mvcs architecture.
    i have started the work. But little bit confused in
    commands-services-events.
    Please help me or give me any references where i can find my answers.
    In service i fetch the information from api in json format. And by trace i
    can see the informations in mediator.
    But i created some vos and want to store these informations in that
    variables.
    so give me any suggestion to overcome this situation.

    Thank you...
    Have a good day.
