Conditional Formatting Pivottables

[Shairal]

I am linking to SQL server and creating a pivottable in Excel '07 with the
data that's returned.

I would like to highlight a row when the last data column is 1.5 times
greater than the total for that row.

I can apply the initial conditional format I want and it works fine, but if
I refresh the data the conditional format gets messed up. It will either
completely disappear or will highlight the wrong area, or not the whole area.


Is there a certain way conditional formatting has to be applied to
pivottables?

Thanks in advance for your help!
