Flexgrid problem - Run time error 381 - Subscript out of range

I have a flexgrid which i am populating, and then when the user clicks on a row, the data for that row is passed to textboxes.

This works fine usually until the form is refreshed
(ie. There is a refresh button, and after it is pressed, if you try to browse around, this error is thrown).
(There is also an update button which calls a refresh, and again after this, if you attempt to browse around, this error is thrown).

Can anyone help me out? What does it even mean and what am I looking for to fix ?

It has highlighted one of the lines I am passing back to a textbox using the .TextMatrix property - but I cant see the problem with this, as before the user Refreshes the page this works just fine!

Someone please help!

This error is raised when you try to access a non existent cell.
For example you pass a column number which exceeds the number of columns in the grid.

The error generally means an Array of something is goofed (i.e., trying to get the 10th element of an array of 9 items for example). Suggest posting the highlighted line for others to view.

I am now getting this quite a lot which I cant understand.

Am passing a number of columns to a grid with one user, and its working fine.

When I use a different user, to pass the same number of columns, it always comes up with an error...

No matter what table I try to pass, it always seems to have an error normally on column 8:

is there something special about column 8 ?

The tables I am passing usually have more than 8 columns - normally they have about 12, but its not liking anything after 8.

Thanks.
