creating calculators

[steve-parrott]

Does anyone know a fairly simple way to construct online calculators?

Specificallly, I'm creating a worksheet that landscape lighting designers can enter such items as lamp wattage, wire length, voltage, etc. When entering these values, I want calculations to be performed in the background to give them resultant values based on predetermined formulas.

Unfortunately, I'm not a programmer and the solution would need to be something simple like a pre-written script (that I could easily customize) or even better a third party vendor that does all the tough stuff.

Thanks for your help.

Not too sure what language you are looking for - but these might help give you a boost:

Thanks for the links. Unfortunately, none of the calculators provided the customizability with the possible exception of the Tigra pro (I'm checking on that.) Any other leads?

Hi Steve,

I know you were asking for help in creating calculators.. but sometimes it's also helpful to see what's being used already. Here are a few examples of online calculators from various lighting-related sites. The GE Lighting site has a selection of excellent resources, including a "virtual lighting designer" which allows you to visualise different lighting schemes 'on the fly'.

Hope that helps,

Hi Steve,

See http://wwww.aspenroofing.com
Then go to Roofing Calculator.

This is a calculator built with Flash and the Input boxes are variable which are then acted on by a math operator within a Function.

Basically, if you know Action Scripting for Flash it ‘s easy to build it to calculate anything.
