How to set up range

Hi. This should be such a beginner’s question but I would like to ask how to set up the range.
My current program is as following.

I put “find the first and the last data” and named the last one as “Number of the last cell”.

Now, I would like to write the same data on column C2 to the last cell of column C.
But, I do not know how to set up the range using “Number of the last cell”.

Could you please help?
