used wildcards in formula sumproduct

I do not understand what your formula is trying to do. However. If A1 is EV:

"*"&$A$1&"*"

will pick up EV AND EVVJ. Can you change EV to something unique?

So... week 1 name 1

EVVJ/16 16/EVVJ EVVJ

will EACH count as 0.5 when you run a SUMPRODUCT looking for EV

It may well be a type of leave day. However your SP formula will NOT work as it stands for the reasons explained at Post 3...

Rule 08: Cross-posting Without Telling Us

Your post does not comply with Rule 8 of our Forum RULES. Do not cross-post your question on multiple forums without telling us about your threads on other forums.

Post a link to any other forums where you have asked the same question. If you have fewer than 10 posts here, you will not be able to post a link, but you must still tell us where else you have asked the question.

Cross-posting is when you post the same question in other forums on the web. The last thing you want to do is waste people's time working on an issue you have already resolved elsewhere. We prefer that you not cross-post at all, but if you do (and it's unlikely to go unnoticed), you MUST provide a link (copy the url from the address bar in your browser) to the cross-post.

Expect cross-posted questions without a link to be closed and a message will be posted by the moderator explaining why. We are here to help so help us to help you!

Read this to understand why we ask you to do this, and then please edit your first post to include links to any and all cross-posts in any other forums (not just this site).

If you have less than 10 posts, do not try to copy and paste the link. Instead, type the link out in your thread.

No further help to be offered, please, until the OP has complied with this request.
