Hi Majib,

Out of the description, I’m going to assume the value is a string value, the list is a list, and you included the brackets to make the value a list?

In that case, if you look at JSON structures, the assignment would need to have the value in “” quotes:

[“165 mg/ml”]

This will give a List, with a single item in the list.

If you have multiple items, it would look like this:

[“165 mg/ml”,“150 mg/ml”,“172 mg/ml”]

Best regards,  
Dawie

Hi Dawie,

Thanks for the reply,

Actually, I am trying to pass the value from json file into the list.  
The json file is like below and has 2 keys for “generic” and “itemstrength” and the value for generic passes without issue.

“level2”: {  
“pharmaceuticalDosageForm”: “Syrup”,  
“primaryUnitOfMeasure”: “EA”,  
“itemstrengths”: [  
{  
“generic”: “Trimethoprim”,  
“itemstrength”: “165 mg/ml”  
},  
{  
“generic”: “Sulfamethoxazole”,  
“itemstrength”: “80 mg/ml”  
}  
],

the error is:  
_For Each\_Product.Loop.ForEach\_itemstrengths.Loop.AddToList\_Strength: Cannot assign value [165 mg/ml] to type [JbZa]_

- —\> System.Exception: Cannot assign value [165 mg/ml] to type [JbZa]\*

Hi Majid,

That probably means you Type has not been set up correctly. Can you send me a screenshot of your type, and also how to assign the AddToList. If you can’t post a screenshot here, please send to support@linx.software.

Best regards,
