Validering

Har ett Javascript på min sajt som w3 validerar jävligt märkligt:

Below are the results of attempting to parse this document with an SGML parser. 

Line 14, column 44: character "&" is the first character of a delimiter but occurred as data

this.ie5=(this.ver.indexOf("MSIE 5")>-1 && this.dom)?1:0; 

If you wish to include the "<" character in your output, you should escape it as "&lt;".
Another possibility is that you forgot to close quotes in a previous tag. 

Line 14, column 45: character "&" is the first character of a delimiter but occurred as data

this.ie5=(this.ver.indexOf("MSIE 5")>-1 && this.dom)?1:0; 

Line 15, column 27: character "&" is the first character of a delimiter but occurred as data

this.ie4=(document.all && !this.dom)?1:0; 

Line 15, column 28: character "&" is the first character of a delimiter but occurred as data

this.ie4=(document.all && !this.dom)?1:0; 

Line 16, column 23: character "&" is the first character of a delimiter but occurred as data

this.ns5=(this.dom && parseInt(this.ver) >= 5) ?1:0; 

Line 16, column 24: character "&" is the first character of a delimiter but occurred as data

this.ns5=(this.dom && parseInt(this.ver) >= 5) ?1:0; 

Line 18, column 30: character "&" is the first character of a delimiter but occurred as data

this.ns4=(document.layers && !this.dom)?1:0; 

Line 18, column 31: character "&" is the first character of a delimiter but occurred as data

this.ns4=(document.layers && !this.dom)?1:0; 

Line 54, column 10: character "<" is the first character of a delimiter but occurred as data

if(this.y<0){

Hela koden ser ut så här:

Varför validerar den inte rätt?
