Custom format Numbers

[jchick0909]

hello,

I am using the following custom format for thousands, but I also need to
show a dash ie "-" if the value is a zero, thanks for your help!!

#,###,

Use something like

#,###,;-#,###,;"-"

Anyway, the 3rd entry (entries separated by semicolons) defines the
appearance of a zero value

1. positive number
2. negative number
3. zero
4. text

What do you want when the cell is negative? The format of a custom format
is:
positive;negative;zero;text

So you want something like:
#,##0,;-#,##0,;-
