error in if

[cimerio]

I just can't understand why the code below shows error in line 13

Code: Select all

#SingleInstance force
SetKeyDelay, 4		
#Include arquivoDados.ahk

Esc::ExitApp

#IfWinActive ahk_class Chrome_WidgetWin_1
{
!a::
if (%CurrentMonth% = "abr" or %CurrentMonth% = "jun" or %CurrentMonth% = "set" or %CurrentMonth% = "nov") 
	%qtdias% = "30"
else
	%qtdias% = "31"
MsgBox, %qtdias%

return
}

It looks like the forum has automatically provided a link to the image instead of an attachment. I have no idea why.

if (%CurrentMonth% = "abr" or %CurrentMonth% = "jun" or %CurrentMonth% = "set" or %CurrentMonth% = "nov") 
	qtdias := 30

I recommend reading about expressions and If in the documentation. Ideas are below. This shows how to refer to expressions. In most situations, % is not used to refer to variables in expressions.

Variable names in an expression are not enclosed in percent signs (except for pseudo-arrays and other double references). Consequently, literal strings must be enclosed in double quotes to distinguish them from variables.

qtdias := 31
If (A_MMM ~= "i)abr|apr|jun|set|sep|nov")
 qtdias := 30
MsgBox 64, Result, % qtdias
