Check out the code behind the Calculate Now button (select button, open Events tab).

The code look like this:
code
var input = Tiggr('baseunit').val();
var from = Tiggr('convertfrom').val();
var to = Tiggr('convertto').val();

var total = input * 0.083;
alert (input + " inches is "+ total + " feet" )
/code

Hope this helps...

Very nice.

I can see how this works and actually understand it a bit.

Is there a line of code that will allow for rounding at a certain decimal place for my results?

One more question.

I see hoe this is calling the input . . . but with a pick list, how can I assign values to each property choice?

How do I assign a value to each measurement type so the var total = input * 0.083; line is modified to show the correct value?

Is this where data mapping would come into play? If so, can you give me a walk through on that too... I can't believe how simple this is once you see how to do it!

Rounding can be done in JavaScript. For example: http://www.javascriptkit.com/javatuto...

Right now the label and the value are the same thing. We are working on separating them. As a workaround, you could have define labels which match the value or check inside the button action which value was selected and use the appropriate value.

No, no data mapping in this case. Data mapping is used when using a service.

No clue what you are talking about , . . could you implement and let me see what you mean . . . I have 26 variations that need to be in the application.

Maybe just add yards conversion to the previous scenario

I modified the action to support yards.. check it out.

I am not seeing any changes to the code. Did it maybe not save?

Not sure what happened, but I restored the screen from history.

I think I got this part now . . . Just a couple of questions and then one more scenario.

var input = Tiggr('baseunit').val();
var from = Tiggr('convertfrom').val();
var to = Tiggr('convertto').val();

if (to == 'Feed'){
var total = input * 0.0833333333333333;
alert (input + " inches is "+ total + " feet" );
}
if ( to == 'Yards') {
var total = input * 0.0277777778;
alert (input + " inches is "+ total + " yard" );

I see that we are converting the "to" in the above lines. What if I need options to change "from" as well as "to"...

I think I will need several lines for this . . . would I need one for every possible combination? And have lines that read something like

if (to == 'Feed')(from == 'Yards'){

I am sorry I am being such a pest.
