Help with input name

Hi,

I am not a Javascript person at all, but I found a script that does everything I need, but the only problem is that the input field name that I need to get a variable posted to had periods in the input name, and I cant simply change the name on the input field.

So here is the line of code that is creating the problem. The InputName needs to be changed to entry.24.single, and I haven't been able to figure out how to do that.

document.forms.MyForm.InputName.value = GETDATA["foo"];

Your assistance is greatly appreciated!
