Infotable column reference as inputParameter

Hi Guys,

i need you help once more.

I have a service which takes one input parameter:

propertyName (string)

I query a DataTable and goes through the results like this

var myTable = infotable result from queryDataTableEntries

var tableLength = myTable.rows.length;

for (var x = 0; x < tableLength; x++) {

    y = myTable.rows.propertyName;

}

however this reference does not seem to work. If I dont use reference and place some existing column name then it works.

Is there any special syntax for indirect reference (like for things, Thing[yourThing].property ....)?

Thanks
