"make new child" fails every time

Every time I try to “make new child” it fails? Please advise correct language.

Use make new row at the end of someRow's children.

much obliged

Thanks also!

I had to change

set LastRowClosedActions to make new child at end of every row of ClosedActions with properties {topic:dateString}

to

set LastRowClosedActions to make new row at end of every row of ClosedActions with properties {topic:dateString}

i.e. changing new child to new row.

I am unclear what the clause > at end of every row of ... actually means, is it at the end of all rows I wonder?
