imacro if else statement javascript imacro

I am stucked here to get the if, else if, statements to work and ask for someone to help. I am using Javascript (scripting interface to iMacro) to accomplish the following executed from the javascript scripting interface. I have a .js file and a .iim file (recorded iMacro file). As you can see, I have big problems to get the if statement correct in the Javascript. Please help!

The end-to-end flow:

1) Check a website for a the word "maintenance".

a) If the word "maintenance" appears, iMacro will return a negative value (<0) and the macro shall start a .bat file

b) If the word doesnt appear, iMacro returns a positive value and the imacro shall continue

2) The imacro (.iim) continues and do an imagevalidation to compare image.

a) If no match on images, I macro returns a negative value (<0) and shall wait x seconds and restart the .iim file again (imacro1.iim)

b) If match on image , I macro returns a positive value (>0) and shall start another .iim-file (imacro2.iim)

My js-file:

' play macro
i = iim1.iimPlay("macro1.iim")

if i > 0 then
Set WshShell = WScript.CreateObject("WScript.Shell")
Command = "C:\start\start.bat"
WshShell.Run Command

else if
i = iim1.iimPlay ("CODE:IMAGESEARCH POS=1 IMAGE=20151228_1550.png     CONFIDENCE=95" > 0)

WScript.Sleep 10000

i = iim1.iimPlay("macro1.iim")

else 

i = iim1.iimPlay("macro2.iim")

end if

My .iim-file (macro1.iim)
