Help with Script

[IamMystic]

With the script enabled, whenever I am in prone, if I shoot, it shoots one bullet and then stand up. It also seems to happen while crouching. Down below is the script. Any help is appreciated.

~LButton::
While GetKeyState("LButton","P"){
Send {LButton down}
Sleep 67
Send {LButton up}
Sleep 67 ; milliseconds
}
return
