Dear Thunkers, I’m building an app to convert text to number and after that this app will sum all numbers. For example: when users type to textbox: TEDDY, app will convert to 75443 and after that it will take a sum of 7+5+4+4+3 = 23. And display 23 in label. Can you help me ☹ ---

There’s a “sum of list” block. Once you split your word up and translate your letters to numbers, it’ll do the rest. ---

If I understand correctly, Label1’s Text value will be “25447” and you want to sum the digits to return 22. These blocks will do that: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/2/5/25d41868b337d74fb5c7a6df514e9040693f1bd6.png) ---

My dear, Thanks for your support. I have build the blocks like that and show the return to label5’s text. But it not work. This is block ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/c/7cf3e617e59fe3936fe0a8ecd07ce4735945332e.png) And this is result. Label5 still is 0 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/c/5cadd407197ebef1893282a01661fe6fb3ff0d22.png) ---

you miscopied tatiang’s block. change the block (see arrow) with \ . copy it from the statement before. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/2/f/2f52c1287377944359d2da08ae6c517e108b6797.png) ---

Right. The algorithm is: ```auto Set the sum to zero Loop through each digit of Label1's Text: In Label1's Text (this is what you're missing), get the character at position i Convert the character to a number Add the number to the sum ``` ---
