Hi, Just to report that in the Snap-to-Place version, the block “Sum of list” doesn’t work using a “Data source” list of numbers. It just displays the values in the list, with a 0 on first place. Example for a list of values composed of 1 or 2 only : 011111221111112111… ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/2/b2db0d2d92672aefc8e5e358b64cb93f033785df.png) ---

Hello @dosantoss I am sorry to hear about your issue. The issue is caused because the values are saved on the table as text To convert them into numbers you need this: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/c/1cb87864652f0cd0e541e163620c61e392bb9a41.png) ---

I wonder if having `text to number` and `number to text` blocks might be useful in situations like this? I suppose that’s a feature request but I think maybe those blocks existed in earlier versions of Thunkable. ---

Hello @tatiang 👋 Of course, you could make a feature request for these. Thank you for your valuable suggestions.
