**SeanCutting**Hi,

I would like to build a form on a page in my website that acts as a quotation form allowing people to measure a width and a height , input theses dimensions and see a price.

Then I would like them to be able via a set of drop down menus to choose other options that can be added to the total giving a final price. Then if they like what they see, allow them to purchase.

Can your software do this for me. If not can you suggest anyone, please?

Regards,

Sean.

**Welvin**Hi Sean,

I'm sure, that is possible in Jotform. Just add the input fields and calculate the totals using our calculation widget: http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form.

Then you can pass the total value to the payment field, follow this guide: http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field.

If you need help about it, let us know.

Thanks

**SeanCutting**Hi Welvin,

Thank you for your quick answer and it looks like I can do what I need to do but I need a little more help if you can? What math function do I need to add to make the quotation work for my form work?

The form needs to give a price for a blind on various sizes of windows. I have a width and a height measurement so create a field for these two measurements. I need to know how to write the calculation to tell me what the quotation costs will be for any width/height combination to add to the form.

An example would be a blind at 120cms high and 230cms wide would cost £303.60 and a 120cms high and 250cms wide would be £330.00, etc

How do I do this?

Regards,

Sean.

**Welvin**Sure!

If you drag the calculation widget to the form, the calculation wizard will open up. Assuming that you have the input fields to the form, you can add it to the calculation, "

**Add Field**" button:If you need to predefine the measurements, you can add those using our checkbox field (for multi-selection) or radio button field (for single selection).

This way, users will just need to select it from the field. Now, you can add a calculation values for each of the field options in checkbox and radio button field. Just click the field > Click "

**Properties**" in gear button > Click "**Show Properties**" to open the additional options:Add the Calculation Values.

I've created this form based on the two options you've mentioned: http://www.jotformpro.com/form/50085438997974.

Let us know if you have any further questions.

Thanks
