Looping through arrays

assgar · #1 (**permalink**) Apr 21st, 2007, 02:21

Hello
I have changed the process code abit so it receives
the data from the form and ensures the data in array format.
This has eliminated my previous error.
The problem I am experiencing is the looping is not
displaying the all contents of the arrays.
Do you have any idea what the problem is and how to fix the problem?

This display the selected data in the arrays

Problem Solved.
Using a for loop to incement the array index syncronizes the array indexes.
I think using a two-dimentional array would be better but I don't how to do that yet.
This is the code that resolved the problem.
