Macro help pls

[starthis]

I've been having a problem with the complete misuse of string , and im not sure what to change the this portion of the code to if any of you can help that would be great. its the line with {string . following is the code

/if (${Defined[cmds-SHORTCUTS]}) { 
      /if (${String[ ${cmds-SHORTCUTS.Lower} ].Find[ ${CurrCommand.Lower} ]}) { 
         /call ShortCut "${CommandText}" 
         /return 
      } 
   } 

   /if (${Defined[cmds-ROUTINES]}) { 
      /if (${String[ ${cmds-ROUTINES.Lower} ].Find[ ${CurrCommand.Lower} ]}) { 
         /call Routine "${CommandText}" 
         /return
