This is a basic misunderstanding...

This forum is mainly about questions about / problems encountered when using LabWIndows/CVI, but not about coding itself. So if you have a question specific to CVI this is the right place to ask.

Since checksums are frequently encountered in data acquisition this topic is covered here as well, but you can and should use the search function of this forum first. You then will find several posts on this subject, e.g. here and here, so why not search (and read) first, try to implement the answers yourself, and then ask if it turns out that CVI reports an error?

Additionally, is not a good practice to open two threads on the very same issue! This discussion started here and could have been kept there. 

But anyway, let's continue in this thread.

I have little to add to wolfgang answer, except that you must have clear which checksum you want to compute  As you can see here, there is not a unique definition of "checksum".
