In DATABASE criteria "Blank Cell" AND ="" are NOT the same things??

Hi, welcome to the forum

A BLANK cell contains nothing
A cell with a formula that returns "" is NOT blank, it contains a formula

If you want to count excluding "", try to use something like <>""

I dont use DSUM, there are other (potentially better) functions to use, such as sumif() and sumifS()

Your post does not comply with Rule 8 of our Forum RULES. Do not crosspost your question on multiple forums without including links here to the other threads on other forums.

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).

@jason

Don't bother too much explaining, although he link to http://www.excelguru.ca/content.php?184 was provided, the OP does not seem interested in it's philosophy ( or forum rules for that matter).
Copy-pasting the text of post #4 in various forums seems to prove it.

Again as I know; There are several forums Separate and Interdependent from each other, and their readers are not completely same.
Why I cannot post the same question into different platforms freely?
I cannot understand this point well.

Are they in reality only one forum (or one organization) but under different domain names?

Sorry, you seem to have mis-understood.
Posting the same question in the same formum is DUPLICATE posting (not allowed either)

Posting the same question on different forums is CROSS-POSTING - and it is considered that on pretty much all other forums. Now, while we cannot stop you from doing that, we ask that you provide links to other forums where you have posted the same question - failing do provide those links is also frowned on.

Most forums ARE "Separate and Interdependent from each other", but many members belong to more than 1 forum, so cross-posting rarely goes un-noticed. When you post on multiple forums, there is teh possibility of multiple members on multiple forums all working on teh same question - on the face of it, this may seem idweal to you, the poster, but consider it from the person answering your question...they spend time and effort on you, only tio find that you already have an answer elsewhere. The more often that happens, the less inclinded members will be, to help you in the future.

For a far better explanation of cross=posting, please take a look at this link...
