I am working on a new workstation with a Word macro that opens an Excel
spreadsheet and copies a chart into Word. The chart to be copied could
be one of two names -- and the code used for checking works on other
workstations but not mine for some reason.

--snip--
1: On Error Resume Next
2: Set GraphExists = xlApp.Charts("Units Graph")
3:
4: If Err = 0 Then
5: ChartExists = True
6: Else
7: ChartExists = False
8: End If
9:
10:
11:If ChartExists = True Then
12: xlApp.Charts("Units Graph").Select
13: chTitle = "Unit Production Forecast"
14: chNameTab = "Units Graph"
15: GoTo CopyGraph
16:Else
17: xlApp.Charts("Funding Graph").Select
18: chTitle = "Funding Production Forecast"
19: chNameTab = "Funding Graph"
20: GoTo CopyGraph
21:End If
22:
23:CopyGraph:
....
--snip--


The Excel spreadsheet being opened has a chart named Funding Graph. On
other workstations it seems to faily silently and go to the Else
statement at line 16, but on one specific one it fails with "Run-time
Error 9: Subscript out of range" (because "Units Graph" does not
exist).

My question is: is there a setting on the workstation/ in Office etc
that may cause this code to work ok in some situations and throw an
exception in others? As a temporary workaround I have begun to
reference the chart by number as opposed to name, but may not always be
the first chart in a spreadsheet so would appreciate any insight into
why this may be happening or a way to cleanly check for a graph
existing (have researched this but not seen an obvious method -- this
may be a stupid question).

Thanks in advance.
