Hi

I'm trying to make an excel document that, when you open it, it pops
up an Input box. It will ask you for a number. Then once you hit
enter it will search the first sheet in the first column and if the
value is different then the one that you put in the input box it will
delete the entire row.

Thank you so much
Laura
