if(select(...

[integral]

What's the difference between these two?

if(select("Yes:No") - 1)

if(select("Yes:No")== 1)

What's the - 1/ == 1 for?

Thank you.

select returns the number of chosen option, starting with 1 (in this case it's 1 for Yes and 2 for No).

if clause is entered if the condition in it does not evealuate to 0, or is not false

== compares two expressions and returns true if they're equal

- 1 substracts 1 from the expression

So, first example, Yes will yield if-condition equal 0, so if clause will not be entered, and No will yield if-condition equal 1, so if clause will be entered.

In second example, you probably know already what will happen

Sorry, I wasn't able to get this part...

Oh... I see, alright. Thank you. Problem Solved.
