I want that the text input(where the amount is filled) to be connected with logic where it should perform according to formula =>(Income - deduction X tax rate = Your Tax ).
For ex I input 5 rupees which is my income and and deduction is 1 so according to formula it will be (5-1) = 4 and that 4 must Multiple with the tax rate. let tax rate 2 so 4x2 = 8%
Is there a particular issue you are experiencing? It looks like you are close but just need to create the formula Income - deduction X tax rate. You can combine multiple math blocks together to create that formula.
I can direct you on which blocks to use and point you in the right direction. If you have a specific question, I can help answer that question, but I can not code all the blocks for you. It does look like you need to mess around with the blocks a little more to gain some familiarity, but once you do, I think you will be able to get the right combination of blocks.
The blocks will look like the formula once you get it correct. It will look like (income - (deduction x tax)). It will be two math blocks and 3 text blocks.
