I'm becoming incredibly frustrated, I hope one of you brilliant people can assist.

I have a link to another workbook that I can't break. It is a link to a previous version of the current workbook.

I have tried the following.
1. Deleted all lines, well past where any data exists including all data and formulas. So effectively it is just a blank sheet.
2. Deleted all data validations (one rule at a time).
3. Deleted all conditional formatting.
4. Deleted all range names.

None of these remove the link.
The only thing that works is deleting the actual worksheet itself from the workbook. The link is then gone.

What am I missing?

Regards
Yoepy.
