I'm having trouble with conditional formatting- so would really appreciate some guidance!

I want to format the numbers in column B, relative to the values in column A.

So if B is equal to or greater than A, format it green. If A is greater than B format it red.

(ahh i can't post an image!) Imagine for example:

```
Col A Col B
123 456
324 290
-50 130
-210 -311
123 123
```

Using the 'Greater Than' function i can achieve this on a row by row basis, but i can't figure out how to do this for a range of rows. So as in the example B1:B10 and A1:A10.

Similarly i can't combine the 'equal or greater than' with the 'less than' functions. But i guess that is simply a case of having two distinct rules that achieve the desired result.
