MAXVISIBLE

MAXVISIBLE(rgeValues)
Returns the largest value from the visible, non blank cells.

REMARKS
* This function excludes hidden cells caused by AutoFilter, Grouping or that have been Manually Hidden.
* You can use the built-in MAX function to include hidden cells.
* You can use the user defined MAXVISIBLEA function to
* You can use the user defined MAXVISIBLEIFS function to
* Similar to the AVERAGEVISIBLE, COUNTVISIBLE, MINVISIBLE, MEDIANVISIBLE and SUMVISIBLE functions.
