No pictures this time but here is what I have changed with the new version of the Cell Watch Form.
If the workbook of the cell you want to watch is not open or has been deleted or renamed etc, the watchbook referred to will be the active workbook. The code will then look for a sheet with the same name. If not found, the active sheet will be referred to. Cell details which are using the active workbook and/or active worksheet show as dark red. Otherwise, cell references with the original workbook and worksheet are black.
This is handy if you do not want to associate the cell references with a particular workbook or worksheet. For example, you could refer to the same columns or rows in any worksheet you work with. This would allow you to watch several different ranges at the same time without the need to set things up manually. Just select the worksheet to see everything you want to see.
Also, you change the value or formula of the cells referred even if you can't see them. Click the white details section(s) on the form and an input box will allow you to edit the cells. The form then updates to show the new details.
