I want to delete the results from the "NI duduction made" & " Less Tax at 20%" from the "Gross Pay" field

the result should be 269.15

but i get 65.3

thanks in advance for any help.

**Jan**Hi there,

If I understand you correctly, you want to add and remove fields in the calculations right? It seems that your calculation fields have default values on it. This is the form you're working with right? http://www.jotformpro.com/form/51070468850960

*Is there a way to use the results of the fields to crate a new calculation.*Yes, you can include or add the specific field in your calculation.

*I want to delete the results from the "NI duduction made" & " Less Tax at 20%" from the "Gross Pay" field.*You can just delete the field in the calculation so that those fields will not be included in the calculation.

Hope this helps. If this is not what you need then let us know and please provide more details.

Thank you.

**siofmon**Sorry I don't think i have explained myself properly

I want the results of the fields to create the sum, because the results are created by different variables.can the results of the calculations be used to make another calculation

if the field calculation is for example x 100, and you input a variable of 5 so the answer is 500,

how do you know use the result, the 500, I want to delete a figure from 500, but i dont know how.

many thanks

Si

cheers

**jonathan**Hi,

**can the results of the calculations be used to make another calculation**Yes. You can just create another calculation and make used of the previous output field result to the new calculation.

**how do you know use the result, the 500, I want to delete a figure from 500, but i dont know how.**I am sorry if I could not easily understand what you meant here.. but I think what you were trying to ask is.. if you can erase/remove the current value of the field.

You can do this by just overwriting the field with another value. So, if you wanted it have no value, then overwrite it with 0 value only.

Let us know if further assistance is needed.

Thanks.

**ashwin_d**Hello,

Yes it very much possible to achieve your requirement. I will take your example (x 100) here to explain how to do this. Here are the steps you should follow:

#1. Add a textbox in your form to allow user to input any number which needs to be multiplied by 100.

#2. Add a "Form Calculation" widget in your form and set the formula to read the value of the text box and multiply it by 100. Please check the screenshot below on how to do this:

If you want to further use the output value of the form calculation widget, you need to add a new form calculation widget or add condition to "Update a form field value". Please check the screenshot below on how to use the value of form calculation widget in another form calculation widget:

Hope this helps.

Do get back to us if you have any questions.

Thank you!
