iLogic Rule Issue

[Anonymous]

Hello There,

I have written a multi-value parameter code populating a few things in the custom i-properties. The rule runs well and fine when created inside a part and it populates the custom i-property as well. However, it throws an error when ran as an external rule. The error definition is stated below :

"Error in rule: Section Code, in document: Solid27.ipt

　

Object reference not set to an instance of an object."

Can anyone help me with this.

Thanks in advance.

Hi Aman,

Would it be possible to copy and paste your code here so that i can have a look?

That sort of error is relatively easy to fix, but i won't know exactly where it is without seeing it
