Hello Folks,

i want to write a function, to call from my Excelsheets.
As param i want to pass either a String or a Cellreference on a Cell
containing the string.

Do i have to declare the param in functionsheader as variant?
If so, how can i check if it is a Cellreference or a String?

I would be glad to get any hint on, where to look and read in OH or
other material.

Greetings,
Thomas
