Scripting problem

I am on lesson 2 of the beginner sheepherder app. I had followed the video but got an error on the script. I thought that it was my error. Then I copy/pasted from the downloaded lessons this portion of the script:
Code: Select all
if intersect (button("sheep"&x), graphic"pen","255") is false and intersect(button"sheep"&x),group"groupControls","0") is false then exit repeat
end if
This is a direct copy/paste. When I hit the Apply button there is this error:
card id 1002: compilation error at line 17 (intersect: two objects are required) near "&", char 92
First, what is causing the error?
Second, for the portion
graphic"pen","255"
what does the 255 refer to and
Third, what does the 0 refer to in
group"groupControls","0"
Thank you,
Linda

Maybe this? It looks like the second intersect is missing a parenthesis:
Code: Select all
if intersect (button("sheep"&x), graphic"pen","255") is false and intersect(button("sheep"&x),group"groupControls","0") is false then exit repeat
--Sefro
edit: 255 an 0 are levels of transparency I think. 255 being completely opaque and 0 being completely transparent.
Here's a link to some extra info about intersect:

edit 2: moved parenthesis ...

Close
Code: Select all
(button("sheep"&x), graphic"pen","255") ---first one
(button"sheep"&x),group"groupControls","0") --second
spot the missing parenthesis

is correct yes? I haven't looked at the sheepherder lessons in quite a while.....

It was indeed a problem with parentheses.
Code: Select all
if intersect (button("sheep"&x), graphic"pen","255") is false and \
intersect (button("sheep"&x),group"groupControls","0") is false then
exit repeat
end if
Thank you for the link too.
