If necessary: You can use both versions side by side…
But at first:
You can use files/links created with 6.x also with 7.x?
Have you tried to copy an older link to 7.x? Did this work?
When you know the name of the reference, can you type it? ( I know this is very old school )
Please provide example files or at least copy one of your working references here.
I have used both versions side by side with two different computers. In fact, that is currently how I get around the problem by install a version 6 on one with similar drives that have similar network references as the computer that has version 7 installed.
By the way, I have installed multiple version 7 from 7.3.x to the latest 7.5.x. None of these works. I’ve also tried multiple version 6.x and all of them works without problems. So this is clearly a problem on version 7.x.
As for example files, I tried just simply create a new ods file that has a table and make sure a named range is defined Then I saved it has a test.ods file. Now create a brand new ods document and try to link it using the external link in the pull down menu. Once I select the test.ods as the linked file, it will show that “No named ranges available in the selected document” message in the “Available Tables/Ranges” box. Nothing complicated. I see no reason in uploading these files.
Is this a problem of named ranges or also a problem to reference a cell as A3 for example.
I don’t think this is a reference cell problem. I can directly copy the reference cell for the linked external files into the cells and it does seem to work. The problem is I cannot provide automatic periodic updates for those cells under “Edit->Links to External Files…” menu. That was how I initially tried to get around the problem only to realize that is not sufficient. I think for some reason, when I used the “Sheet->External Links…” menu, it is unable to find the named ranges in the document even when I know for a fact that document does indeed has named ranges already defined.
