Validateur: comment résoudre cette erreur?

Question

Je reçois cette erreur dans le validateur:

Line 47, Column 187: character "&" is the first character of a delimiter but occurred as data 
…num, silver diamonds. cartier tiffany & Co. $18 WALKING LIBERTY DOLLARS $15… 



This message may appear in several cases: 
You tried to include the "<" character in your page: you should escape it as "&lt;" 
You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe. 
Another possibility is that you forgot to close quotes in a previous tag. 

Comment le régler?

Answer 1

Vous avez oublié d'échapper à une esperluette.

Remplacer & par &.
