Title: Amount Field – Conditional Last modified: August 24, 2018 --- # Amount Field – Conditional * Resolved [manpasand](https://wordpress.org/support/users/manpasand/) * (@manpasand) * [7 years, 11 months ago](https://wordpress.org/support/topic/amount-field-conditional/) * Hello, I have a problem with Conditional Logic for filling the amount. I am ONLY asking the GROSS INCOME from the user and rest of the two calculations (home expenses and business expenses) I am doing with the form. I have setup max amount for Home Expenses ($3000) and Business Expenses ($2000). * Now the problem is, if business expenses goes beyond to that amount, form input should show only $2000 BUT if it is less than $2000 input shows actual figure( e.g. $1584). * I facing problem in the Formula Builder to show the amount. * How can I fix that?

Am i right? * If so in your ‘Income Total Amount’ field should use this formula: * `Math.min([Gross Income], 2000)` * Thread Starter [manpasand](https://wordpress.org/support/users/manpasand/) * (@manpasand) * [7 years, 11 months ago](https://wordpress.org/support/topic/amount-field-conditional/#post-10623212) * Yes, you are right. * Getting Syntax Error when I use `Math.min([Gross Income], 2000)` OR `RNFRound Math.min([Gross Income], 2000)` in the Formula Builder. * Plugin Author [EDGARROJAS](https://wordpress.org/support/users/edgarrojas/) * (@edgarrojas) * [7 years, 11 months ago](https://wordpress.org/support/topic/amount-field-conditional/#post-10628114) * Yes sorry for that, the validator doesn’t understand that Math.min, please try to execute the formula and see if it works.
