Use of Range and Last row to add borders around cells.

After searching and reading some other posts similar to what I'm looking to do, I have decided that I could use a little help.

The code I have right now that does not work is...

Range("A1:H" & LastRow).Borders.LineStyle = xlContinuous

What I'm doing to taking a report that is supply in a Word Document and analyzing it in Excel. The macro I have created removes columns that are not needed and inserts a few new ones. The sheet has columns from A:H and I would like to have borders around all cells both empty and with content. However, every time I need to do this the row count will change. I feel that I'm on the right track, but not sure what corrections I need to make for it to work.

BTW... there is no hurry on this as I'm leaving the office soon and will not return until Monday.

Thanks in advance.
