This is not natively supported in Excel but you may like to look at Laurent
Lonngre's Funcustomize add-in which is freely downloadable at:

Is it possible to add tooltips or helper tips to my custom fucntions so
the
user knwos what parameters need to be entered to use my fucntion? I'm
currnetly using VBA but could use another lanuage (c#, VB) if that would
help.

Thanks,
