 * Hi,
 * I just want to input a simple calculator, for example
    140% (default text) X 
   field number (input value) X field number (input value) X 0,025 (default text)
   = total. What is the formula that I can use. Thank you in advance

 * Hello [@steelrods](https://wordpress.org/support/users/steelrods/),
 * If the first field is a “Single Line Text” control, you should convert it in 
   a number. So, assuming the fields are: fieldname1 (the textual field), fieldname2
   and fieldname3 (the number fields) the equation would be:
 * `parseFloat(fieldname1)*fieldname2*fieldname2/100`
 * Note, javascript is a case sensitive language.
 * An alternative would be emulate the percentage field with a currency field, entering
   the percentage symbol as the currency, in whose case the equation would be simply:
 * `fieldname1*fieldname2*fieldname2/100`
 * and that’s all.
    Best regards.
