Hi @CYJ ,
Could you tell me the data type of author field?
Please notice that Split(authorinput.text,",") will return a table, while label1.Text will return a text.
You could not update the same field with two different data structure.
Since the record number that "Split(authorinput.text,",")" returns is dynamic, so you need to create another collection for this. Then use this collection to update author field.
Try this formula:
ClearCollect(test2,Split(AuthorInput.Text,","));
//create another collection for split result
ForAll(test2,Patch(Test,Defaults(Test),{author:Result}));
//update multiple records in Test collection by using data in test2 collection
Collect(Test,{author:Label1.Text})
Best regards,
