then i need to put a math formula in and have the answer displayed in the 3 box.

Hello,

I created a sample app for another user a while back that has calculations in it. This should help with what you are asking. Down load the app and look in the app_custom.js file to see the javascript.

A quick three ha’pence worth… If the formula is at all complex, Google ‘JavaScript Math’ to determine the syntax for the more tricky functions.

Hope this helps.

Without knowing your box names or what formula you need here is a quick sample of what it might look like. You could place this in a button action Run Javascript.

var myNumber1 = $(‘#m1-myscreen-textField1’).val();
var myNumber2 = $(‘#m1-myscreen-textField2’).val();

$(‘#m1-myscreen-textField3’).val(myNumber1 + myNumber2);

thanks for the help,
but i am new to the whole programming side,
did some visual basic, which was easy
but i purchased this as it was a visual program
and with you have given me is good
but where do i put it, or how do i put it in.

i am doing this as these formula’s are known
to the diabetes educators and i was wanting
to give this to everyone to help them,
but what you have given me is with this
program is easy to you but to me a beginner
is really hard.

thanks anyway

I do not mind helping.

Create the screen as you want and upload a screen shot with the calcs you are wanting and I will post an example like I did for the other user to learn from.

Cheers…

CF=100/TDD

TDD=short+long

there maybe 2 more pages but i havent decided yet
about them, this is the main page that needs the calculation.

[Stu Wade]

The last piece of information we require to be able to complete the calculation is: how many decimal places would you like to be displayed in the output fields?

[Stu Wade]

Try this – I have zipped up a version for you

Gentle bump, the OP has not yet responded.

[philipdk]

sorry for the delay in getting back to you, this is the trouble with shift work
it needs to be a 2 decimal point, and though it works great the worst part
is i dont know how it was done.

it looks like java code you imbedded into it, which means if i need to do more
with this program i need to learn java, maybe i should have purchased
microsoft visual studio instead of mobione as i have had abit of work
with visual basic.

i am working on my second screen which will consist of a text box
but needs to have one or both the answers pasted into the
explication to give people more info.

but many thanks it is a start
