You're right, my last fix only got half the bug — pasting 241,538 was still being read as 241.53. The input was trying to be "helpful" by swapping commas for dots (or vice versa) based on what it guessed you meant. Sometimes it guessed wrong. New rule: your budget's number format is the rule, no translation. If you're on comma-thousands/dot-decimal, commas are always grouping and dots are always decimals. Same idea for the other two formats. So 241,538 now reads as 241 thousand, just like you'd expect. As a bonus, this also fixed a quieter bug in the math cells — 1,000+500 used to evaluate to 501 (the comma got reinterpreted as a decimal), now it's 1500. Thanks for pushing back — the simpler rule is the right one.
Appreciate your hard work on this app...It's really nice to use!
