I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
Thanks. That was the first time, as I am novice in coding, so pardon me for initial errors.
code is as follows
btnCalculate.setOnClickListener{
/* I am trying to add base price + taxes, if any + shipping costs if any + other fees, if any to calculate unit price,
when I enter all 4 values then the app works, and I leave even one blank (as it may not apply, then the app crashes, so how could

Hope this formatting using backticks would be better and easy to red.
