Get List Of All Values Corresponding To A Value In The Adjacent Column

[emmye998]

very sorry Mister, "Fox"
For your efforts with me, thank you for your patience my sir
If we changed the title of the post to:
"Get a cell change depending on the change all values​​, even if the value of similar"
We'll get to the solution
It seems I did not explain the topic well yet:
I want to change the cell "D1" change depending on the "C1" Well this is happening.
2 - I want to be changed (D1) even if the condition is a duplicate value corresponding to this condition
In other words, if the "M1" in the column "A" corresponds to "2" in the column "C" shows "2" in cell "D1". If we wrote this "M1" in cell "C1".
If the "M1" in the column "A" corresponds to "5" in the column "C" shows "5" in cell "D1". If we wrote this "M1" in cell "C1".
If the "M1" in the column "A" corresponds to "2" in the column "C" shows "2" in cell "D1". If we wrote this "M1" in cell "C1".
