Q: How do i determine if an error is in any cell in the entire workbook with Excel VBA?
Normally errors will be divide by 0 or #value errors, but this list is not exhaustive (or is it? - i don't know if more exist)
Is there a way to determine if a cell contains an error then to skip over further processing in my script without spitting out a debug/warning/error message.
something such like
if value in current.Workbook.cell is error then go to <jump>
OR
if value in old.Workbook.cell is error then go to <jump>
where jump is a marker at the end of an if statement but within a loop.
the script compares values between two workbooks and updates the current workbook with colours to show difference.
I have no VBA experience at all. but i get the gist of the script i have been given.
thank you kindly.

Select the worksheet you want to check for errors. If the worksheet is manually calculated, press F9 to recalculate. If the Error Checking dialog is not displayed, then click on the Formulas tab > Formula Auditing > Error Checking button.
A fast way to find all #REF Excel errors is to press F5 (Go To) and then click on Special, which for short is referred to as Go To Special. When the Go To Special menu appears, select Formulas, and then check only the box that says Errors. Click OK and that will automatically take you to every cell that has a #REF!
There are three types of errors in programming: (a) Syntax Errors, (b) Runtime Errors, and (c) Logical Errors.
You can skip cells with errors by using the VarType function. For example:
If VarType(ActiveCell.Value) <> vbError Then
' do something
End If
The VarType function is also very useful to validate the data type. For example if your code expects a date value but sometimes encounters text, you can use this function to vet the data and handle exceptions gracefully.
