Calibration page on startup then times out

Hi All,
I'm trying to make a Calibration Page that times out after 30 seconds, this part is ok, i would like to add an onscreen count down time to this screen showing how long before the page closes and your returned to the Welcome Screen...See code below. It's mostly working except that the onscreen countdown just keeps overwriting the same place, and it goes to the Welcome screen after about 2 seconds.
Any help is always appreciated.

Code:

 If ShowingPage("Calibration Page") then Begin
 
 TextPos(335, 373);
 SetFontSize(20);
 
 DrawText('', 60 - TimerTime(3));
 Delay(1);
 If timertime(3) = 0 then;

ShowPage("Welcome Screen")

 end

 

DrawText only writes the foreground. You need to erase the background first by drawing a filled rectangle.

The semicolon is terminating the if statement. Remove it.

 

Thanks Ash,
I did look for the commend to erase the background but couldn't find anything to do it...

Oops missed that,
Will do that background square now...

 

Yep, so far so good, thanks Ash.
