If what you are actually trying to do is to automatically incorporate a
suffix onto a number, (not to TEXT), this can also be done with Custom
Formatting of the cell(s), to the format of
# "YourString"
Otherwise, Max's solution will work just fine, or, if you really want to
automatically CONCATENATE the value from B2 to the value whenever typed in to
A2, then VBA is the only way to do that.
