VFP: Containers in Grid Column

Within a grid column I have a container, that has a line, two labels and a backcolour that all need changing depending on values from a table (each row is showing one record). However, whenever I change one, the entire column is changed, every row becomes identical - how do I get around this?
(I've read the 'Tips' on 'backstyle_access' and although the procedure is run for each row of the grid, the pointer in the table never seems to move, so all the results are identical! I'm clearly missing something.)
(Also unfortunately I'm running VFP6, so any solutions need to be pertinent to that version - sorry!)
Anybody with any ideas? It's driving me mad!!
