Variable used without being declared error

[jackiemagpie]

Hi I'm new in programming and when I try to wait colour to continue the action, I get this error.

Variable used without being declared.:
$waitpixel=PixelSearch (673,154,842,302, $WaitPixelColor,0xF8F4F8)
$waitpixel=PixelSearch (673,154,842,302, ^ ERROR

And That's my code. Anyone knows why getting error ?

While 1
    $waitpixel=PixelSearch (673,154,842,302, $WaitPixelColor,0xF8F4F8)
    If Not @error Then ExitLoop
    Sleep(10)
WEnd

Welcome to AutoIt and the forum!

The error message perfectly explains what causes the error

Local $WaitPixelColor = 0xF8F4F8, $waitpixel
While 1
    $waitpixel=PixelSearch (673,154,842,302, $WaitPixelColor)
    If Not @error Then ExitLoop
    Sleep(10)
WEnd

Declaring variables is one of the basic steps when starting to write scripts in AutoIt and is perfectly explained in the help file!
