G'day PLtech,
Please do the following at these cells
D55, D56, D75, D76, D77, D78, D96, D97, D98,
Click on the cell change the format from text to general then click in the formula bar then press enter.
Please do this individually.
This should fix all your problems across the spreadsheet.
That comment your referring was not directed too you. It is part of my signature.
If that does not help, I will upload my alteration on your file.
Cheers
