[Solved]TStringGrid EGridException index out of range.

I'm probably doing something really, really stupid.
Code: Pascal
[Select]
[+]
[-]
fpaths
:
=
TStringList
.
Create
;
fpaths
.
Delimiter
:
=
';'
;
fpaths
.
StrictDelimiter
:
=
True
;
fpaths
.
DelimitedText
:
=
INI
.
ReadString
(
'Font paths'
,
'paths'
,
''
)
;
StringGrid1
.
Width
:
=
GroupBox1
.
Width
-
16
;
for
i
:
=
0
to
fpaths
.
Count
-
1
do
begin
if
fpaths
.
Strings
[
i
]
<>
''
then
StringGrid1
.
InsertRowWithValues
(
n
,
[
fpaths
.
Strings
[
i
]
]
)
;
end
;
Can anyone advise me what it is?
I've tried setting the rowCount to 1 and clearing it with TStringGrid.Clear.

Where is n from in
Code: Pascal
[Select]
[+]
[-]
StringGrid1
.
InsertRowWithValues
(
n
,
[
fpaths
.
Strings
[
i
]
]
)
;
I guess, it should be i.

*sigh*
Code: Pascal
[Select]
[+]
[-]
for
i
:
=
0
to
fpaths
.
Count
-
1
do
//You are using "i" as iterator
begin
if
fpaths
.
Strings
[
i
]
<>
''
then
StringGrid1
.
InsertRowWithValues
(
n
,
[
fpaths
.
Strings
[
i
]
]
)
;
//You are using "n" as Row-Identifier
end
;
Spot the mistake
EDIT: Why even in such a convoluted way with that InsertRowWithValues?
Why not read the INI-Stuff into a FileStream, and then use LoadFromCSVStream?

Thanks,
Well spotted.
Yes the 'n' was a legacy item in my code that I hadn't noticed.
The reason that I'm loading from an INI file is that I have multiple items and the Font paths are just one of them.
