NOTE -When we click on the ‘Add Price Scheme’ button, section should get open as shown in above  first screenshot.

when we change pricing scheme from dropdown we need to open some sections as shown in screenshot 2,3,4.

when we add any price scheme with markup option or fixed price option we want one condition to add here  – minimum markeup percentage  

we are going to add one button  send project for manager approval in project section  so that button we want to disable if approval amount is = to or < then calculated project value using minimum markeup percentage, and show message your project value is already discounted. 

example –

Project value with maximum marke up percentage is 1000

project value with minimum mark up percentage is 800

disable approval request buttion if approval is for 799 or less then 799

unable it if project value is 999 to 899.
