Have tried that but no joy.
I have included code for the events below.
form1.#subform[0].WS.Row4.Tn3::initialize - (JavaScript, client)
if (this.rawValue == null)
{
Injury1.presence = "hidden";
}
form1.#subform[0].WS.Row4.Tn3::calculate - (FormCalc, client)
// sum using FormCalc
$ = Sum(Row3[].n3[])+(RowFCE[].n3[])
form1.#subform[0].WS.Row4.Tn3::validate - (JavaScript, client)
if (this.rawValue >= 1)
{
Injury1.presence = "visible";
}
else if (this.rawValue < 1)
{
Injury1.presence = "hidden";
}
