write a function to determine if cells have names
 

I am doing a roster and would like to know how to do a function to make
sure cells certain cells have names present
eg. cells a1 : a5 should have names present - is there a function in
say a6 that if all cells (a1:a5) have a name present a6 = true, and if
any cell has no name present a6 = false (or any other text)
I want this to make sure all cells are filled in with a name

If the cells can only contain names or be blank, something you can ensure using
data validation, then

=COUNTA(A1:A5) = 5

should do what you request.

Correction: Data validation cannot "ensure" that a1:a5 contains names; but
could be used to restrict possible entries to TEXT, and also to certain minimum
length of text.

For example, the validation formula:

=and(ISTEXT(A1),len(a1)2)

would restrict entries to be text and be at least three characters long.

thanks,

tried counta - started with false when no cells had names, changed to
true when all cells had an entry, but when I deleted a cells contents
the counta result stayed with true - any ideas

When you deleted the data did you use a space or something?
a lot of functions treat a space as an entry.


i would recomend rather than Counta
Counta counts functions concluding ""

=if(countblank(A1:A5)=0,"true","false")

1. Did you delete using the <delete key, or did you type in a <space?

2. Did you set up the data validation for A1:A5 as I suggested?
