FYI... If anyone wants to know what the correct example content should have looked like, this is it:
Example context (json):
{
"respondentscolumn0": {
"respondentlink": [
"HTML of respondent link1",
"HTML of respondent link2"
]
},
"respondentscolumn1": {
"respondentlink": [
"HTML of respondent link3",
"HTML of respondent link4"
]
},
"respondentscolumn2": {
"respondentlink": [
"HTML of respondent link5",
"HTML of respondent link6"
]
}
}
}}
