Hi Rob：
I want to use DisplayText to display the count for the for loop. However, DisplayText can only display text in the for loop and cannot obtain variables. Here is my simple code. I hope I can get your help. Thank you.
Quote:
sp.Sleep(600);
var ress = Number(inputbox(" "));
for (ddi=1; ddi<=ress;ddi++){
sp.CreateTimer("test", 5, -1,
var info = new DisplayTextInfo();
info.Title = 'Test';
info.TitleAlignment = 'Center';
info.Message = ddi;//Only text can be displayed here, and variables cannot be obtained.
info.MessageAlignment = 'Left';
info.Duration = 3500;
info.Opacity = 0.7;
info.Location = 'top';
info.TitleFont = new Font('Segoe UI', 12, host.flags(FontStyle.Bold));
info.MessageFont = new Font('Segoe UI Semibold', 12);
info.BackColor = 'black';
info.Padding = 15;
info.UsePrimaryScreen = true;
sp.DisplayText(info);
sp.DeleteTimer("test");`);

sp.Sleep(1000);
sp.SendKeys("1")
sp.Sleep(1000);
sp.SendKeys("2")
sp.Sleep(1000);
sp.SendKeys("3")
sp.Sleep(500);
sp.SendKeys("~")
}

Timers execute in a thread. There are more than 1 script engine and your for loop is using the thread where the variable is defined, so it doesn't exist in the timer's thread.

However, you need to cast the variable to a string since it (.Message) accepts an object and it's creating a reference issue.

In this case, you don't need a timer (removed some stuff to simplify):
Code:
var info = new DisplayTextInfo();
info.Title = 'Test';
info.TitleAlignment = 'Center';
info.MessageAlignment = 'Left';
info.Duration = 3500;
info.Opacity = 0.7;
info.Location = 'top';
info.TitleFont = new Font('Segoe UI', 12, host.flags(FontStyle.Bold));
info.MessageFont = new Font('Segoe UI Semibold', 12);
info.BackColor = 'black';
info.Padding = 15;
info.UsePrimaryScreen = true;

sp.Sleep(600);
var ress = 4; // Number(sp.InputBox((" "));

for (ddi=1; ddi<=ress;ddi++){
    info.Message = ""+ddi; // Cast variable to string
    sp.DisplayText(info);
    sp.Sleep(1000);
}
