AHK stuck with function with value outside of it - autohotkey

Question

Those if doesn't work, because test() doesn't take value from outside, but I have no clue how I should write code if I put it inside...
Any suggestions?
SetTimer, test, 2000 ;I started off with 1000 then worked up to this number to confirm this was happening
number := 1
test:
test()
return
test(){
if WinActive("program") {
ImageSearch, foundX, foundY, 2000, 0, 2560, 1440, target.png
if (ErrorLevel = 1) {
if (number = 1) {
CheckMap(z := "star.png")
number := 2
}
if (number = 2) {
CheckMap(z := "like.png")
number := 3
}
if (number = 3) {
CheckMap(z := "question.png")
number := 4
}
if (number = 4) {
CheckMap(z := "cross.png")
number := 1
}
}
}
}
CheckMap(x){
ImageSearch, foundX, foundY, 2000, 0, 2560, 1440, %x%
if (ErrorLevel = 0) {
MouseGetPos, StartX, StartY
Click, %foundX%, %foundY%
MouseMove, StartX, StartY
}
}

Found some help, that I needed static number, also fixed if to else if, now works perfect
SetTimer, test, 2000 ;
test:
test()
return
test(){
static number := 1
if WinActive("program") {
ImageSearch, foundX, foundY, 2000, 0, 2560, 1440, target.png
if (ErrorLevel = 1) {
if (number = 1) {
CheckMap(z := "star.png")
number := 2
} else if (number = 2) {
CheckMap(z := "like.png")
number := 3
} else if (number = 3) {
CheckMap(z := "question.png")
number := 4
} else if (number = 4) {
CheckMap(z := "cross.png")
number := 1
}
}
}
}
CheckMap(x){
ImageSearch, foundX, foundY, 2000, 0, 2560, 1440, %x%
if (ErrorLevel = 0) {
MouseGetPos, StartX, StartY
Click, %foundX%, %foundY%
MouseMove, StartX, StartY
}
}
