Multiple Switch-case problem

Hi, i have an m.file with 6 switch-case like so

if true
  % code
end
switch value
  case 'tptk'
      switch actionpre
          case 'rn' 
              switch texture
                  case 'fd'
                      switch pos
                          case 'ip'
                              switch opponumber
                                  case 'hu' 
                                      evaluation=' No info yet.';
                                  case 'multiway'
                                      evaluation=' No info yet.';
                              end
                          case 'oop'
                               switch opponumber
                                  case 'hu'
                                      evaluation=' No info yet.';
                                  case 'multiway'
                                       evaluation=' No info yet.';
                               end

The inputs for each switch come from a multiple choice GUI. The problem is that if i do each switch case separately, for example in the command window, i get to the result. Instead, if i run the entire code (quite massive, each switch-case is from 2 to 11 choices), it stops at some point without giving me the solution. Any help?
