But that's not a big deal as nothing gets done first time through the loop except for $get_hloopRow1 getting incremented. The next time through the loop, because $get_hloopRow1 is now not zero, the first conditional gets executed. You add some html and the first value from the array to $text to the string and incremenent $get_endRow. All subsequent times through the loop, nothing gets done because the $get_endRow == 0 condition fails. $get_endRow never gets incrememented again. that help at all? -robin
