New to SuiteScripts and trying to create a script which sets the value of one text field from another text field when value is entered when creating a new event.

function setcustomfieldA()
{

nlapiSetFieldValue('custevent_fieldA', 'custevent_fieldB' , true );

}

For the custom Entry Form - Type CRM, Subtype Event

Set the following values on the Custom Code tab for the custom Entry Form

Script File : Uploaded my file with the above code
Field Changed Function : nlapiSetFieldValue

Saved changes and tested custom form.... nothing happens so what am I doing wrong???
