Parray
i have version 0.27.6 and follow an online tutorial have the code below: no error to run the script and the Parray appears in my first library after clicking instance. a popup window titled "except caught" but no content in the window. and the program closes afterward.
please help show where it could be wrong.
code starts from next line.

"""
This sample PCell implements a library called "MyLib" with a single PCell that
draws a circle. It demonstrates the basic implementation techniques for a PCell
and how to use the "guiding shape" feature to implement a handle for the circle
radius.
NOTE: after changing the code, the macro needs to be rerun to install the new
implementation. The macro is also set to "auto run" to install the PCell
when KLayout is run.

First of all, you can format code by placing a line with three backticks before and after the code (I change it for you, otherwise it's very difficult to read).
The error message is this:
I don't know why it does not show up in your case, maybe you should try the latest version.
So the fix is simple: just add "self" in front of rownum and colnum:

Matthias,
thank you very much for helping fix the bugs. it works right now.
Hi I am using version 0.27.12 and trying to do Parray. I can't change the shape with partial. Can you please help me with that? Please check the code below.
@soumeniit Could you explain in more detail what you are doing and what is your expected outcome?
Thanks,
Matthias
@Matthias, I am just trying to make a custom Parray. I want to do partial change in one macros but can't change.
. Can you please help?
You have to first create "variants". Use "Edit/Selection/Make Cell Variants". This will break the array and create a new cell specific for the location where your selected shape is in. After that you can edit this cell without affecting the other instances.
