Puzzle 1: Message in a Bottle

Yes! - now I have both the cipher text: MEXORMECPGEOORDIE.UITKNORKIKNLFORPLE, and the keyword:CLUE.
I have everything I need to decrypt this message. To do that, I will need to draw a table.
Because "CLUE" is a 4-letter word - I know I'll need a table with 4 columns.
Then I need to split the cipher text string into 4 equal parts:
1-MEXORMECP 2-GEOORDIE. 3-UITKNORKI 4-KNLFORPLE
Each of those sub-strings is 9 characters long, so my table needs to have 9 rows.
I'll write the keyword at the top, and then work out the alphabetical order of the letters.
All I need to do now is populate the table columns vertically - put string 1 in the "1st" column, string 2 in the "2nd" column, string 3 in the "3rd" column, and string 4 in the "4th" column.
