Formula broke, need commas back. (complicated)

If your formula currently uses ; like:

=SUM(A1;B1;C1)

• Replace it with commas:

=SUM(A1,B1,C1)

• You can do a quick Find/Replace (Ctrl+H) in the formula bar for ; → ,.

Without the formula and the digital environment (operating system, Country, storage medium, etc.), unfortunately, we can only guess, and I'm not good at guessing.
