Matching arrays to build tables

Hi, I have 3 dynamic arrays which is related data pulled from a mySQL database, the first being day $days[],second being amount $amount[] and third being a specific code $code[]. What I need to do is display a table with 1 to 15 in the left hand column (days) but where the array $days[] contains an item I need to add a column with the related data but add the values of amount if there are two entries for a given day, something like the below. $days[] = ('2', '2', '5'); $amount[] = ('150', '100', '90'); $code[] = ('LAC', 'LAC', 'NCA'); +++++++++++++ Day |Amt. | Code | 1 | 0 | | 2 | 250 | LAC | 3 | 90 | NCA | 4 | 0 | | etc. until 15! Any help would be greatly appreciated my code is getting jumbled and confusing :(. Thanks
