Question: Attempted to set unknown property 'value' on component 'DataTable0'

I have two procedures X() and P() which both are working. (See attached worksheet )

LL_100)_Quandl_Get_D.mwLL_100)_Quandl_Get_D.mw

When I put:

z := X(P());
Do(%DataTable0 = z);

I get an error:

Attempted to set unknown property 'value' on component 'DataTable0'

why??
