```I have a small range of cells (less than 100) in which I need to
count the
cells that are blank.
What is the best way to do this?

I was trying something like "=COUNTIF(C11:C103,(CELL("Type",b)))".But
that
just did not work.

Thanks to all who helps me with this simple problem.

```
```
=SUMPRODUCT(ISBLANK(C11:C103))

```In a related (I think) question, what formula could be used to identify
the last row in a spreadsheet with data in it?   It's a similar
situation as the OP, in which new data is inserted as a new row at the
bottom of the sheet.   I want another worksheet to be able to pick up
certain fields from the last row of data, but haven't been able to
figure out how to locate which row is last (with data).

A1=a
A2=b
A3=c
A4=d

What I'm looking for is a formula that would tell me, in the above
data,
that row 4 is the last one with data.

Thanks for any help!

I know that this is not what you asked for exactly, but coupled with
CELL() or COUNTBLANK() function, might allow you to establish the row

The following allows me to get the last value of the column (F) in
sheet1 (used in my case in a summary table that lists the final value in
a column that lists the running balance of my bank account)...

=OFFSET(\$'sheet1'.\$F\$6,COUNTA(\$'sheet1'.\$F\$6:\$'sheet1'.\$F\$9633)-1,0)

Assumes the range \$F\$6: to \$F\$9633 has continuous data - essentially it
returns the number of rows/cells with data, so will not work if your
array or range has blanks (unless the number is static or can be
predicted).

So in your example... COUNTA(A1:A1000) will return 4, knowing that you
start from A1 allows you to extrapolate that the last row is A4.

```
```
=SUMPRODUCT(MAX(NOT(iSBLANK(c11:c999))*ROW(c11:c999)))

give the number of the last row with data in the range.

```

And all these tricks are completely obsolete if you know how to
navigate, expand and edit spreadsheet ranges with a couple of  keystrokes.
By the way: If you would use a database in the first place the editor of
your data would not even need to know that.

```
```
```
No doubt but Michael asked a question and others helped by answering. If he wanted to know how it should be done or what would be the best way of achieving an end result I presume he would have asked. The fact is he did not actually provide any guidance to why he needed to do what he asked (which is quite common on this forum), only asked if it could be done.
```
```
IMHO, the tone and content of your response is not very helpful and belittles other peoples attempts to assist. Outlining the keystrokes mentioned and how databases might assist in what you presume he needs would have been more useful.
