First i just want to make sure I have the carry detector NAND circuit correct. I have to Design a carry detector NAND only Circuit when the sum exceeds 9, if it does, the led light should light up. What I am having trouble with is understanding how to change inputs on X,Y, QA, QB, and QC on EasyEDA to see the outputs.

This is what my circuit looks like

OBJECTIVE To design a combinatorial circuit utilizing an adder IC. To test circuits using 7-segment numeric display. PROCEDURE 1) Given a 4-bit binary adder (74HC283), design a circuit performing the following functions depending on xy selection: Function Helpful interpretation 00 F = Q F=Q+ + 01 F = Q + 1 F = Q + 0 + 1 10 F = Q + 2 F = Q + 2 + 0 11 F = 0 + 3 F = Q + 2 + 1 where: Q is a 3-bit binary input variable Q = QCQBQA provided from the sequencer (assign 4th input bit QD=0). Hint: xy can be used as a carry bit and/or input to the IC adder 2) Provide the input sequences for A and B using switches.
