@JLWest,
It is rather impossible to tell what's wrong without seeing the actual code that produces that error.
however:
apicollections.pas(576,57) Error: Expected another 1 array elements
generally indicates that the number of items in the TDayNames is one item short.
Did you perhaps mismatched or mistyped a "," somewhere ?
Also note that TDayNames is actually a variable, and that it is a bit strange to prefix that with a T (as that is usually used for type declarations).
