Data validation to prevent keying in of specific text.

[tcca85]

Hi experts,

Kindly assist, I'm trying to plan roster for my team, they can only work a maximum of 8 consecutive days.
So the work days cells, I will key as "1" and "off" will be off days. So I want validation to prevent me from keying "1" after 8 consecutive consecutive "1".

Or in more details is it possible to detect 8 consecutive different text "position" from a list of table which lists labelled?

Welcome to the MrExcel board!

I think that we would need to see a sample of your worksheet layout. MrExcel has a tool called “XL2BB” that lets you post samples of your data that will allow us to copy/paste it to our Excel spreadsheets, so we can work with the same copy of data that you are. Instructions on using this tool can be found here: XL2BB Add-in

Note that there is also a "Test Here” forum on this board. This is a place where you can test using this tool (or any other posting techniques that you want to test) before trying to use those tools in your actual posts.

Hi, you will need to adjust the formula to match the location of your data. This assumes that the first cell in the plan is in A1 and the validation starts in cell in A9 (there's no point in putting validation in previous cells as they cant possibly be in error.

the formula is:

=sum(A1:A9)<9
