With the following statement:

Debug.Print Application.WorksheetFunction.VLookup("a", "range1", 1)

If I hightlight Vlookup and hit F1, I see an error

"The page cannot be displayed"

Properties upon the error message shows that it tried to access the
following address:

res://C:\WINDOWS\system32\shdoclc.dll/dnserror.htm#mk:@MSITStoC:\Program%20Files\Micr osoft%20Office\OFFICE11\1033\VBAXL10.CHM::/html/xlmthVLookup.htm


On the above statement, I can however highlight "WorksheetFunction" and
press F1 and see the correct help page.

Any ideas what's wrong ? At time of installation I did a Full install so
everything should exist.



Regards,


Steve
