This is my Custom Function and I want to edit it

There's an ampersand missing on the "8th" line. I've taken the liberty to add it and reformat for better legibility:

Case(
Round(Number * 32; 0) = 32; // Fraction is closer to 1 than 31/32
" +1";

Mod(Round(Number * 32; 0); 2); // Some odd number of 32nds
Round(Number * 32; 0) & "/32";

Mod(Round(Number * 16; 0); 2); // Some odd number of 16ths
Round(Number * 16; 0) & "/16";

Mod(Round(Number * 8; 0); 2); // Some odd number of 8ths
Round(Number * 8; 0) & "/8";

Mod(Round(Number * 4; 0); 2); // Some odd number of 4ths
Round(Number * 4; 0) & "/4";

Mod(Round(Number * 2; 0); 2); // 1/2
Round(Number * 2; 0) & "/2";

"" // Fraction is closer to 0 than 1/32
)
