Conditional formatting with 6 conditions?

[proepert]

I'm using Excel 2000 which has a limit of three conditions, I have 6. If you could just get me started, I still don't understand VBA enough to do this.

In cell A1, the color is set to red. I want A1 to turn green when all 6 conditions are met:

1. Cell B1 has a valid value from its pull down list, no other value, and not empty.
2. Cell B2 has an integer, no decimal places allowed, and not empty.
3. Cell B3 has a valid value from its pull down list, no other value, and not empty
4. Cell B4 is not empty.
5. Cell B5 has a three decimal place number greater than zero.
6. Cell B6 has a single letter from A-Z only.

Please see the attached workbook.

Thank you for your continued help.
