Runtime error on blocks

[dimitrisba]

Hello im trying to make a painting app and when i draw it show the following : The arguments , [223.27272], [428.72726] are the wrong number of arguments for DrawLine
Note: You will not see another error reported for 5 seconds.
I have deleted every block and put the all again and still the same error. Can somebody help me. I will attatch a photo of my coding here.

Thank you.
