Why can't I call two image flow modules on the PHP page?

Why does the PHP page call two image streaming modules? why did I build a PHP page? why does one module work? The code is as follows: & lt; div & nbsp; id = "www_qpsh_com" & nbsp; style = "overflo PHP why do I not move the two image flow modules on the page?
I made a PHP page, and a flow module was designed to flow.
Why do two flow modules not flow?

The code is as follows:




 

Var fx = 0;
Var speed = 20 // the greater the speed, the slower the speed.
Www_qpsh_com2.innerHTML = www_qpsh_com1.innerHTML
Function Marquee (){
If (fx = 0 ){
If (www_qpsh_com2.offsetWidth-www_qpsh_com.scrollLeft <= 0)
Www_qpsh_com.scrollLeft-= www_qpsh_com1.offsetWidth
Else {
Www_qpsh_com.scrollLeft ++
}
} Else {
If (www_qpsh_com.scrollLeft <= 0 ){
Www_qpsh_com.scrollLeft + = www_qpsh_com1.offsetWidth
}
Else {
Www_qpsh_com.scrollLeft --
}
}
}
Var MyMar = setInterval (Marquee, speed)
Www_qpsh_com.onmouseover = function () {clearInterval (MyMar )}
Www_qpsh_com.onmouseout = function () {MyMar = setInterval (Marquee, speed )}
Function left (){
Fx = 0;
}
Function right (){
Fx = 1;
}
Function linkmenu (id ){
Document. getElementById ("linkmenu1"). className = ""; document. getElementById ("linkmenu2"). className = "";
Document. getElementById ("linkmenu" + id). className = "linkon ";
Document. getElementById ("linkcont1"). style. display = "none"; document. getElementById ("linkcont2"). style. display = "none ";
