i have a two multidimensional arrays $path and $record i have to do looping and update the array values there is some issue with array declarations i am not able to find out.
Console Error: Uncaught TypeError: Cannot read property '0' of undefined at the line if($record[$path[a][icell]][j]){
$record has been assigned values before like in the lines $record[i][2] = true; same is with $path but values are retrived from array not assigned just 5 lines before the line error occurs that is $path = [[$start]]; so why the error occurs when both the arrays are used combinedly if($record[$path[a][icell]][j]){.
if u require jsfiddle i will provide but i guess it doesn't serve the purpose contains lot of other irrelevant scripts too so unnecessarily making the code overwhelming. Hope i made myself as clear as possible u need any clarity i will sure provide
