This can happen if any row is added during runtime.
If a row is added or deleted, we should call oCol:WorkMergeData() and oBrw:Refresh().

In case you are browsing DBF it is desirable to SET FILTER TO !DELETED() so that oBrw:keyNo() always returns a correct value.

Line 11714 is Eval( ::oBrw:bGoTop ) and this can not be NIL, unless this method is called before setting the browse completely.
I hope when you call oCol:WorkMergeData, the browse is already visible on the screen.

What I quickly choose the date and press oBtnDal possibility of a mistake is higher. The error occurs when executing commands oBrwZbr:SetFocus().

When you use SQLRDD, OrdKeyNo() does not work. Consequently oBrw:KeyNo always returns 0. The feature of MergeVert does not work for SQLRDD.

If you use SQLRDD you can do basic browsing and many advanced features of xbrowse are not available.
