Excel 98 help needed PLEASE!!!!

If I use

Tell app “Microsoft Excel 98”
set XMaxVal to MaximumScale of Axis (xlCategory) in ActiveChart
end tell

in AppleScript, XMaxVal is an integer, so 6.5 becomes 6 and my data is off.

is there some other way to get this data into AppleScript so that it stays as it is?

I hope you can understand what I’m asking, after 48hrs of this, I’m not sure if I know what I’m asking
