Excel VBA error with sum formula

[brightwayhr]

Hi All,

I have an spreadsheet which consist of employee data and there revenue to generate an automate invoice.

here is an image link

https://1drv.ms/i/s!AnOR9mvtWzlzc6NUs4vHUtxOI5c

M21 is the total cell which has name range as Total
M22 is the StTax as name range.

The grand total has to be M21:24

The error is Grand Total is not including M23 and M24 as the formula which is applied in M22 cell was Total-StTax as named range.
However I tried recording macro its not working out can anyone edit my below vba code as per formula and share the proper code.

M21 is Total amount of M
M22 is 14% from Total
M23 is 0.5% from Total
M24 is 0.5% from Total
Grand Total = M21:M24
