I am new to developing applications in Excel and was
hoping someone could point me towards a tutorial/article
that would help.

I have 5 categories of job titles and I currently have to
provide enough rows and sheets for the maximum number
that could possible be needed. It is overkill on 90% of
projects and it also makes the file size very large.

What I would like to do is create a workbook that will
create new sheets and new rows based on a number selected
from a listbox.

Can anyone help? Is this fairly straightforward?
