Hi,

0. Name the range containing the 1000 primes Primes
1. On the other sheet select ALL the data, for this example, I will assume
A1 is the first cell of the selection.
---
In 2003:
2. Choose Format, Conditional Formatting
3. Choose Formula is from the first drop down
4. In the second box enter the formula:

=OR(A1=Primes)

5. Click the Format button
6. Choose a color on the Patterns tab (or any available option)
7. Click OK twice.

In 2007:
1. Highlight all the cells on the rows you want formatted
2. Choose Home, Conditional Formatting, New Rule
3. Choose Use a formula to determine which cell to format
4. In the Format values where this formula is true enter the following
formula:

=OR(A1=Primes)

5. Click the Format button and choose a format.
6. Click OK twice

If this helps, please click the Yes button.

Cheers,

Worksheet 1 consists of a single column containing the first 1000
prime numbers. Worksheet 2 consists of multiple columns of numbers.
Is there a way to highlight with a chosen fill color all cells in
worksheet 2 containing prime numbers from worksheet 1? Thanks.
