return zero from a blank cell

[Eric]

=E8-(B9+IF(ISBLANK(G8),0,G8))

I cant get this to work
If G8 is empty return 0 else return the value from G8 so that
the end result is E8 - B9 if G8 is empty ELSE E8-(B9+G8) if G8 has a value

Where did i go wrong?

Another problem:
E9 to E368 contains decreasing dollar values that eventually fall below
Zero. I want to find the first Exx cell at or below Zero and return the A
Cell from the same row (which is a date)
so for example,
H1 I1
Zero Date =Cells.Item(MATCH(E8,E368,-1), 1).Value

RowNum Col A Col E
335 Jun 1, 2003 $25.00
336 Jul 1, 2003 $15.35
337 Aug 1, 2003 -1.00
338 Sep 1, 2003 -16.00

so the formula would find Row 337 and return the Date in A:337 which is Aug
1, 2003 and Cell I1 would show that date

Thanks
Eric

Blank is zero, all you need is =E8-(B9+G8)

On the other

=MIN(IF(A1:A20<0,A1:A20))

which is an array formula, so commit with Ctrl-Shift-Enter.

Where is that option? Excel version?
