I created a function and placed it in an Excel Addin. I installed the addin on my machine by going to Tools -- Addins and browsing for my .xla file. When I use the addin on my machine, I can type =xyz() to call the function. It works just fine. I loaded this addin on another person's computer and I can only use the addin if I type =AddinName.xyz(

What am I missing. Why can I not just type the name of the function

Thank yo

Mike
