Ok, I checked on the grid relationship - eventually skimmed the grid down to the object reference only and built it using code. Turned out that the problem was a typo in one of my column source references. Didn't get any error message to that effect until I used the line code! Corrected that within the grid and it is displaying on the screen now but I still need to filter the records shown to those matching the parent table. At least I'm passed that other hurdle! Thanks for the help!!
