Repost your question with PROPER Mathematica syntax {} is use ONLY for lists, tables, iterators etc. Use parentheses for qrouping. If you believe parentheses will cause problems, breaking e.g. A into A1, A2 e.t.c. for compactness and simplicity. Execute the following command FrontEndExecute[{HelpBrowserLookup["MainBook", "1.2.5"]}] See also the following link http://documents.wolfram.com/mathematica/Tour/ I and many others will be respond to your question as soon as you make the proper changes in A and B.
