Numbers that arrived as text, and will not behave until you convert them.
The payment gateway export puts every amount in as text, which is why the column will not behave like money. Convert each amount to a real number in column C.

This is the grid you start with. Cell references in the task — B6, C2 — point at the row numbers and column letters below.
| A | B | C | |
|---|---|---|---|
| 1 | Reference | Amount (text) | Amount |
| 2 | PAY-4471 | 1240.50 | |
| 3 | PAY-4472 | 89.99 | |
| 4 | PAY-4473 | 376.00 |
Exports from payment systems, bank portals and older databases routinely deliver numbers as text, and the damage is quiet rather than loud. Try =SUM(B2:B4) on the text column: it comes back 0. Not an error — a confident zero, because a range contributes only the numbers in it and text is skipped however much it looks like one. The same silence puts 9 after 100 when you sort, and leaves a lookup matching nothing. VALUE is the one-step fix, once you know to look for it.
