मैं कोशिश कर रहा हूँ करने के लिए जोड़ें 2 outputs, और उनके परिणाम में एक तीसरे/चौथे पर प्रदर्शित 7 खंड प्रदर्शन. प्रत्येक उत्पादन में दिखाया गया है अपने स्वयं के खंड क्रमशः. चौथी प्रदर्शन किया जा रहा है एक दो अंकों की संख्या (अधिकतम किया जा रहा है 14, Min किया जा रहा 0). मैं एक त्रुटि हो रही है यह बताते हुए कि मैं लिखने के लिए की जरूरत के सभी उदाहरणों के मामले में "जोड़ें". नहीं यकीन है कि जहां यहाँ से जाने के लिए. किसी भी मदद की सराहना की है ।
