multiple cell check and setvalue

[kwdennis]

  // Set the options based on account type automatcially and save those settings for reloading data
  // if your account is VIP options will default to VIP you can then manually set to Yes to show ownership
  // these settings will be saved if you drop to Premium and back to VIP
  // have multiple cells to check would like to add an array type check if possible
 
  // just started using google sheets for this
 
  // any help would be apprecitated with setting up some type of multi cell check setvalue

  var AccountType = myDashboard.getRange("Q15").getValue(); // checking the account type value to set the ownership default settings 

    if( AccountType === "VIP" )
    { 
      if( myDashboard.getRange("G23") === "Yes" && myDashboard.getRange("G23") === "VIP" ) // check cell for values
      {
      // leave the setting alone     
      }
      if ( myDashboard.getRange("G23").isBlank() === true ) // check if the setting is blank
      {
       myDashboard.getRange("G23").setValue("VIP"); // set the default value here based on account type
      }   
    }

      if( AccountType === "Premium" && myDashboard.getRange("G23") === "Yes" ) // check cell for values
      {
      // leave the setting alone     
      }
      if ( myDashboard.getRange("G23").isBlank() === true ) // check if the setting is blank
      {
       myDashboard.getRange("G23").setValue("No"); // set the default value here based on account type
      }
    
 
      if( AccountType === "Free to Play" && myDashboard.getRange("G23") === "Yes" ) // check cell for values
      {
       // leave the setting alone
