Does this part work?
Code:
tail -1 `overvieuwFunction`
It does not look correct to me...
Anyway, the problem you're asking about is that you try to use: `some-command` nested within another set of ` and `. That doesn't work.
If you use the bash shell, it can be solved by using $(some-command) syntax. This does the same as the back-tocks (``), but does allow nesting.
Code:
echo "TEXTB $(tail -1 $(overvieuwFunction) |cut -d" " -f1) TEXTC";
