Creating a Flag based on cell value
 

Hello. I'm trying to create a Function based on the cell values within a
range to create a flag (1 - on or 0 - off) in another.

The problem is the same value when it repeats has to have a different
flag value. For example

Range-x Range--y
Key ----- 1
Hello ------- 1
Bye -------- 1
Key -------- 0
Yes -------- 0
No --------- 0
Key -------- 1
This -------- 1
That -------- 1
Key -------- 0
Fix -------- 0

So the flag needs to alternate designation off of a particular value
when it appears in the range and alternate in groups.

When it first appears, everything underneath it is a "1". When it
appears again as a trigger, everything underneath it is a "0" until it
appears again, and so on. I hope this makes sense.

Any help here would be greatly appreciated.

Thanks

Dan

You shouldn't need a UDF for that. Try this formula and drag down:

=IF(MOD(SUM(($A$5:A5="Key")*1),2)=1,"Yes","No")

It is an array formula so be sure to use ctrl shift enter.

in cell Y1
=MOD(COUNTIF($X$1:X1,"Key"),2)

then drag fill down the column

would also work.

I've been out done! Nicely done Tom. I guess I get stuck on array
formulas sometimes. Better to avoid them if you can.
