I’m trying to recall how many values are there in list viewer but it return as 0 even tho there is a value ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/2/429572aede9f7f2eab314e0f3f7ae72bb0a04b48.jpeg) Blocks ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/e/6e8beae82c261f5d1e7cccc25a161d097e4de1d2.jpeg) ---

Check the length of the thing you are filling the list viewer with. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/d/7d9d5e136e67106a65c8f046f3a88db17dac6f5e.jpeg) Check the length of the first set of blocks. I notice the interesting delimiter too. Maybe that’s causing the issue? ---

Can you test it using same delimiters? ---

why are you using a special delimiter? you should measure the data block you use to fill the list viewer, don’t measure the length of the list viewer itself. ---
