Check the same values and delete if same, sort rows in sentence

Hi to all,

I would like you to help me with this:

1)
I have plenty of rows filled with data. I d like to check if C and E is of same text and if so, than make null C column.

2)
In next cycle, the macro will sort columns in sentence of F E D C

3)
Next and final thing i need in this script is:

Check if C and D is same

if so

then

also check if in C:C is same text (i think, that it can check only the next row, because of sort... so the script will not be so tough and time cost)

if not same, delete actual C

if same, leave actual C as it is

Thank you for helping in this :)
