The problem is with the eval(). It is not needed for your purpose.

What eval does is look at the string and re-interpret before it is executed.

for example you can build a string such as
“document” + “.f1″ + “.t2″ + “.value” and pass that to the eval() function.

You can also build variable names and use eval to reference those variables. For example:

var i;
var textBoxValueAssign;
for (i = 0; i < 100; i++)
{
textBoxValueAssign = “f1.txt” + i + “.value = ” + (i+1);
eval (textBoxValueAssign);
}

The above code assigns the values of 1 through 100 to the inputs on the form named “f1 called “txt0″ though “txt99″.
