You look ready to learn how to use lookup tables.
tbh I'm new here.
What does that mean?
Your blocks are highly repetitive. Take Spinner2. AfterSelecting as an example. Instead of checking the line width over and over again, why not set the line width to the selection directly?
For Spinner3, why not try something like this?
Canvas.aia (2.5 KB)
The Canvas1. Dragged event is invoked when the user has scribbled on the canvas. It just draws the line.
Okay, I'll try.....
Here is an example of a lookup table for color names:
What's the error?
Show your new blocks. My AIA was tested and it is working.
If you're making a scribbling app, ideally you have to incorporate the Dragged event as I showed. The PaintColor and LineWidth properties only apply to drawing activities after setting these properties.
is linewidth a Dictionary?
are there all your blocks? I did not see the code for drawing.
i said whether the error is still the same that time 
Oh sorry. Yes, I was having the same problem that time.
My main problem is not with the drawing of lines. it's about changing the colour and width of the line.
Are you creating a scribbling app?
