Hi everyone i'm basically having an error coming up when trying too run a simple script, the error says,



Error: Variable used without being declared.

This is my first day using Autoit, it was working fine untill i changed the pixel color so not sure what too do...

Here is the script,

$coord = PixelSearch(0, 0, 1279, 799, 0xFF0000)
If Not @error Then

Any help would be great thanks!

When you changed the colour you must have changed the line

$search = PixelSearch(..

to $coord = PixelSearch(..

The script you show has nothing to set any values in $search or even to make it an array.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
