Ajay,

We may have a terminology problem here. If it's really a user-defined
function, it can be called only in a formula, not from a button. If the
macro is a sub (not a function), then it can be assigned to a button.

Hello All
Quick question can I attach a user defined function from Personal workbook
to a customized button, I know I can right mouse click the button and
assign
macro but the list does not include functions.
Probably doing something v wrong help would be much appreciated
TIA
