Union Query asking for a parameter value

I have been asked to fix this query which I did not write. When I run this I get
Enter Parameter Value boxes in this order:
PHM_MAC_CHRT_HST.PTMEDREC
PHHST_GENNAME_IDX.PTMEDREC
PHHST_ORDERS.PTMEDREC


Here is the union query below.  Please help me rewrite this so it does not ask for the parameter values.
