Perhaps you could elaborate on how your question relates to
Microsoft Office, which is what this newsgroup supports.
Your question will be less incoherent if you remember to include
basic information such as what version of Office you're asking
about, which particular Office application this problem occurs
in, your operating system version, and the exact verbiage of any
error messages you see when the problem occurs. Vague statements
like "unable to" or "not functioning" usually do not provide
enough information for anyone here to offer an informed
suggestion. We can't see your screen from here. Tell us what
you are trying to do, what you are clicking on to do it, what you
think should happen when you click, and what actually happens
when you click.
