I realize whats wrong Im just not certain on how I fix it
if i enter a letter this line obviously cant convert it
double isales = Convert.ToDouble(sales);
How do i fix

$tryparse

This method was made for this explicit reason

It checks if your string can be converted into a given numeric type, and if so, converts it

im finding it a bit confusing to understand, where would i put this in my code and what would i need to change

You'd use it instead of your convert

Ahhh I see ive got it in now and its working thank you

How would I return overtime so I can use it down there

result is your parsed number

yeah but how do i still get it down to use there because changing overtime to result it still cant reach it

You're trying to use the variable in the outermost scope

So you need to declare it in the outermost scope

And instead of out var result in your tryparse, you can then use out thatOuterVariable

so do i put int overtimetotal = (overtime * 15);
inside of the parse one

Try and see

Well, that's not how you do it, then

$scopes

im confused so where abouts do i put it

You're trying to use the overtimetotal variable in the outermost scope

So you need to declare it in the outermost scope

That's the tl;dr

ohhhhhhhh isee now thank you so much
taking me a while to wrap my head around it lol
