I've tried a couple macro's I've seen online, but I can't seem to make a
macro work to hide lines on my worksheet.

I've got a quote worksheet with rows 13:130 available for quoting.

In column A is where the quantity gets filled in automatically from a
previous tab via a macro.

I'd like this worksheet to automatically hid the any rows on this tab that
do not have a quantity in column A.

Also, I've got my worksheet o "Auto-fit" the rows in this worksheet and the
worksheet that feeds information into it via a Macro to "Auto-Fit" rows to
the description of the product, however it doesn't happen. Any idea what I
should do here?

Many thanks!
