Don't know how to output this array

[paul_wilkins]

THOSE are the results I expected! Now I'll do some homework and see how to limit the decimals to 2 places. Thanks for your help!

You can use .toFixed(2) to limit numbers to two decimal places.

OK, I figured out where to put your 2-place code. One final thing -- I should be able to enter a number in the ratio box without adding any numbers in the Spur and Pinion boxes at top. But the code won't execute. Any reason why it won't read the top form?

Your attached code from earlier plus the fixes seems to work fine in that regrad.

Show us what you are using now, and we'll find the problem.

Zipped HTML. Thanks for your time!

I won't at this station tomorrow. I'll be back in on Friday.

The code works for me in Google Chrome when I don't enter the gears and just type in my own ratio number.

Let's see how it goes in Firefox. That seems to be okay too, although Firebug does provide this warning:

Element referenced by ID/NAME in the global scope. Use W3C standard document.getElementById() instead.
Line 144

That divide.onclick should instead use getElementById

How about in Internet Explorer? Ahh, that errors saying that divide is not defined.
Now you know of what should be looked in to.

I am using this on the iPhone only, so it only needs to work in Safari. If there's no workaround, then we can consider this finished. The people will be very happy to have it as is!

I really appreciate all your hard work. You are truly a Javascript Guru!

The Windows version of the Safari web browser doesn't seem to have any trouble either. I'll see if I can find an iphone simulator. Ahh, here's one.
iBBDemo2 - Cross Platform iPad and iPhone Simulator

That seems to work too, with your test code that I have up at:
Gear Ratio

I really appreciate all your hard work. You are truly a Javascript Guru!

You're very welcome. Thanks.

I just tried it in Safari on the Mac. Typing a number in either of the top boxes generates "not valid."

Strange!
