else if ( ( p1 - p2 - p3 < 0 ) || ( p1 - p2 -p3 > 100 ) )
alert("point out of range.");

the above code is part of a javascript and checks if the value is between 0 and 100.

I need to changed to something like

else if ( ( p1 - p2 - p3 < 0 ) || ( p1 - p2 -p3 > value of the edit box with the name MAX ) )
alert("point out of range.");

thats because the value in the edit box with the name MAX can be changed

Can anyone please tell me how can i do it ?

Thanks in advance.
