How to rerun a form without erase all of the inputs

when I Enter necessary inputs in my form and click on show results button, a function calculates and puts the results to some arrays and then show them in

a datagridview,

now my problem is when I re click on show results button it gets me the same table but with huge and wrong numbers!!!!

what should I do?

I don't want to refresh form because I should re enter all of inputs again!

I want when user once clicks on show results and decides to change some inputs and re click show results button, it get a table with true results!!! :(
