Hi. Can anyone please help me? Following code create array of checklistboxes after user enter a value. I also have a json file:
 
{
"length": 38,
"masking": [ 1, 2, 6, 10, 15],
"date": "2018-08-07 10:10:10"
}
 
I want to be able to map user selection of checklistboxes to "masking" in json file. Also, how to assign values to arr of checkboxes e.g. checkbox[0] = A, checkbox[2] = B etc. We don't know how many checkboxes will be needed.
 
If user selects checkbox with indices 1, 3, 4, 6 it should map to json file and display value of selected checkboxes.
 
Thanks in advance.
