PHP or Javascript Calculator

In Progress


I need a basic javascript or php website calculator, whichever is easiest. I will also need a basic html page with a calculate and a clear button.

The calculator should be based on the attached excel spread sheet.

There are a total of 8 calculated fields and all are simple math calculations and are indicated with an x to the right of the calculated cells.

There are a total of 6 user input fields and are indicated by the red font color. The values that are in the cells currently need to be set as default values within your script and replaced in the calculation only if a user should override the default value.

All field values should round the same as the attached spread sheet.

If a field used in the calculation is left empty the script should generate an error message.

When the user clicks the clear button the calculator should reset.

My maximum budget is $50 USD

Please supply a link to work samples when bidding.

Thanks for your interest!
