<![CDATA[ReferenceError on Meta Data Source script]]>Hello,

This is related to Core 3.6.4 / Meta 3.6.2.

When attempting a simple script

var myTotal = (p1148.value + p1164.value + p1068.value + p22238.value);
return(myTotal);

I receive the following error that I was hoping someone could shed some light on -

ReferenceError: "$EXEC" is not defined at line: 23 at line: 23

Thank you

I had a global script using $EXEC
Once I removed that the script would execute.

Seems like line 23 would indicate that script of 2 lines has a lot more to it than what you shared. Which usually means there are global scripts being put into the context.

One thing to check is the script permissions. I know that in later versions of mango we restricted the environment when it does not have superadmin permission. I am not sure how the $EXEC call will perform in that situation.

I checked and on this particular instance of mango I had made the changes referenced here

and here

var myTotal = (p1148.value + p1164.value + p1068.value + p22238.value);
return(myTotal);

I am not able to reproduce this error on the same version of mango. Could you provide more information?
Is this on the v3 UI or legacy UI?
Do you get that error when trying to validate the script?
Can you export you points JSON and paste is here?

I corrected that and continue to have the same error.
