Error Message when generating OTF font

[Del]

Hi,
I am using FontLab Studio 5 and am getting an error message when generating to OTF font, which is:

[WARNING] <Flatpack> The feature file OS/2 overrides TypoAscender and TypoDescender do not sum to the font bbox size!

Does anyone know what this means?  And what I should do to create a "clean" OTF font...

Thanks,
Del

This means that you have conflicting entries in your dimensions fields or that the entries you selected do not total a possible number.  OS/2 Typo acender-decender cannot exceed the total number of units you are working with.  If you have a UPM of 1000, then the ascender value plus the descender value cannot exceed 1000.

Check your "Key Dimensions"
