[GNC] Getting Quotes for Funds

[aeg]

Hello,
I'm seeking help with setting up Security Editor to track the performance of two funds I've invested in, as GnuCash seems to dislike something about my setup.
I'm using GnuCash version 5.13 (Build ID: git 5.13-9-ge22c406547+(2025-10-12)) with Finance::Quote: 1.66 on a Windows 11 Professional computer.
The two funds are:HSBC Global Strategy Balanced C AccVanguard LifeStrategy 60% Equity Acc
I've tried various ways to ensure that I've entered the correct information, but nothing has worked yet! This is what I have so far...
Name: HSBC Global Strategy Balanced C AccSymbol/abbreviation: 0P0000WN82.LDisplay symbol: HSBCNamespace: FUNDISIN, SEDOL or other code: GB00BDCZ7F86
Name: Vanguard LifeStrategy 60% Equity AccSymbol/abbreviation: 0P0000TKZK.LDisplay symbol: VLS60ANamespace: FUNDISIN, SEDOL or other code: GB00B41XG308
For the "Quote Source Information", it seemed like "Multiple" - "U.K. Funds (FT Funds, MorningstarUK)" was the obvious choice, but when that didn't work, I tried "Single" - "Alphavantage" as used successfully for my other shares, but all my attempts to "Get Quotes" have reported errors for both funds.
I'm sure someone will immediately identify what I'm doing wrong, and I'd appreciate any help with pointing me in the right direction.
Kind regards,AlanG
