The issue here is that you have created a column "Name" with quotes,
which means it is case-sensitive.

You are then trying to access it without quotes which means it gets
folded to lower-case "name" (look carefully at the error message).

If you quote the name when you create it, ALWAYS quote it. If you never
quote names then you won't have any problems.

It might be that the webmin module quoted the column-name for you
without your knowledge. You'll need to consult your webmin documentation
for details.

It looks like the table is being defined with the column quoted, like
this:

create table one ("Name" text, moredefshere...)

but accessed without quotes, like above.  Whether a database folds to
upper or lower case, the columns need to be accessed consistenly, either
all quoted or never quoted.  An application that mixes quoting and not
quoting identifiers is going to have problems.
