Hi Alex,

var firstSeqNum = disData[0][0];

If I intend to set a seqnumber based on the above statement, when the grid is building and this field is not populated it throws an JS error disData[0] has no properties.
How can I handle disData[0][0] having no value without throwing this error??
i.e if firstSeqNum has a value do something otherwise alert('no seqnum set');

Appreciate any help
