Just wanted to ask … How do I Calculate ( range From 1 Square foot to 300 sqft ) x $20 = $6000 ( $6000 is the minimum ) either 1 or 2 or 3 or 300 will end with result $6000 - The number will calculate after 301 and up as normal .

any help would appreciated.

Hi Khoa. You could use conditional logic to show one of two fields (one number field for 1-300 sqf, and the other a number field with the calculation enabled, for 301+). If the number they enter is under 301, then show the first field equal to $6000.

If the number they enter is greater than 300, then show this other number field, which is a calculation that is $20 times the number field they entered.

Will that work for you?
