How to use a BLANK in a complex formula

The Excel table is setup as follows
Across the top there can be up to 6 territories
Each territory has two columns (one is a count column and the other is a Win column)
Down the side is a row for each month.
The variables are that there could be anywhere from 2 to 6 territories active for that sheet.
The objective is to get the WIN column for the one that has a BLANK value in the Count column display a value of 1.  So if there are only 2 territories naturally the one that has no value in the count column will have the value of 1 in the win column.  But when you start adding 3, then 4 and up to 6 territories the formula because a lot more complex.  If there is no territory name then there should be no values in the Win column at all.  There can be a value of ZERO in any of the columns as this is a reportable value.  ONLY a BLANK can get a Win value.
Could really use some suggestions on how to get around this.

Hope I understood correctly.. you basically want something like..

=IF(AND(NOT(ISBLANK(A1)),ISBLANK(A4)),1,0)

so basically territory is not blank, and Count is blank returns 1, otherwise zero

Would probably work best if you name your territory ranges.

This partially works.  Thanks for this.  I did tweak it based on your recommendation.  I still have a small issue.  if I have 6 territories they all populate as soon as  I put one value in any of the columns.  Is there a way to only populate the WIN value only after the others have been inputted.  Pierre
