Template talk:RQ:Harvey Pierces Supererogation

Error
Hi,, what did I do wrong with the Module:string command in this template? I am trying to find out the rightmost character of a page number. Pages 1–16 are repeated in the work, so my intention is to ask editors to specify pages 1A–16A when referring to the first set of pages. Thanks. — SGconlaw (talk) 11:54, 10 April 2019 (UTC)
 * It looks like you used Module:string right, but was generating an error. (Not sure why the error mentions   rather than   because the parameter is  .) Stripping off any final letters seems to fix it. — Eru·tuon 19:58, 10 April 2019 (UTC)
 * oh, of course. Silly me. Thanks. — SGconlaw (talk) 01:55, 11 April 2019 (UTC)
