Your code doesn't select the range - you need to use

Excel.Sheets("ALLIncidents").Range("A1").Select

but first you also have to make sure that "ALLIncidents"
is the active sheet:
Excel.Sheets("ALLIncidents").Active

unless of course you know for certain that it is active - but
better safe than sorry..

As a general rule it's not usually necessary to select cells,
and it tend to make macros run slower (as well as possibly
confusing users by losing their initial selection). Instead
you can do things like:

Dim MyCell as Excel.Range
Set  MyCell = Excel.Sheets("ALLIncidents").Range("A1")
MyCell.Value = "Hello, World!"
