Need some help using Natural Logarithm/LN Calculation

I have a couple text boxes as follows:

text1 = number that doesn't change (6.5459673)

text2 = number that will change based on input from another text box (box1F6)

in excel the calculation would be: 6.5459673 (or text1) * (LN(F6))

I tried doing this:

var nBox = + getField("box1F6").value;

event.value = math.log(nBox);

but that didn't even put a 0 or any input for that matter. 

Any help is appreciated! Thanks in advance!

Should work, only it's Math.log(), not math.log()... JS is case-sensitive, so the latter would cause an error.

Was there an error reported in the console?

Is this code entered into the Calculation Script?

Do you know that the value of "box1F6" is a number?

And math needs to be capitalized:  Math.log();

Try this. add this line to  your code immediately after the "getField" line

console.pritnln("Val=" + nBox);

Here is a tutorial on using the Console Window.
