#### Finding Missing and duplicated Numbers

```I have a table

name a        15
name b        16
name c        18

There will be 80 names and 54 numbers (1 to 54).

I need a formular that would search the list of numbers and report back any
duplicate numbers and missing numbers.

Is that possible?
```

```Here is a simple solution. I put my names in A6:A85 and numbers in B6:B85
If your numbers are somewhere else change the references to \$B\$6:\$B\$85 in my
formulas but do not change reference to A1.

In C6 enter this formula =IF(COUNTIF(\$B\$6:\$B\$85,B6)-1,"Duplicate","")
Copy it down the column by double clicking the fill handle
Numbers that are duplicated will be so indicated

In D6 enter this formulas =IF(ISNA(MATCH(ROW(A1),\$B\$6:\$B\$85,0)),ROW(A1),"")
Copy down the column
Numbers that are missing in column B will be displayed in column D

Add space after each numbered or bulleted item
I need to make rather long lists of paragraphs that are several lines long. The numbered list feature forces a new number and a new line upon hitting enter. this is expected behavior. However, I need a space between the items to make each item stand out. In Word if I hit enter again, a new number is issued as expected. However if I arrow up to the first empty space and hit the backspace, the number will be removed, the following number will be changed to next sequential number and the empty line remain.

Finding a Median
I'm trying to write a query that will return a median for various values taken from a previous query. I've seen some suggestions in my searching, but I haven't been able to get them working. They are also all from before 2003 and refer to Access 97 and 2000. Has any functionality been added to 2003 for this? Or is there a non- code-based way to do it?
