hello, i’m doing an app to calculate school grades so that you put in each insert text the grade you got in a bimester and show on a label the sum of the grades without having to click any buttons, the way i’m trying it’s not working. could someone please help me? ![thunkable%20blocks](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/8/b881d56835967f4d5085d76d3f87f4c740cf0b51.png) ![thunkable](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/0/5087b633cc50f0139cca663bd7a409a99d11b618.png) ---

Where is the ‘resultado porto’ label on your Screen? Are you typing a plain number in to the Text Input like “60”, or are you typing something like “60%”? Jane ---

The label does not appear on the image but it is after 4 text input. The numbers I am trying for are simple example “60”. thanks Joao Vitor ---

hi @barbosadantasvpj, I tried this in my app and didn’t have any issues with it. The calculation was performed and the value was returned correctly. ![calcualte%20grade](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/3/938b158ea77b3cfe2881206236bf582f3270bc79.png) I’ve used the exact same blocks that you have (as far as I can see anyway!) ![49](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/4/d4aa5ad15657fe8517efe4a22d40feb8c7a41c33.png) ---

Ahhh…now I understand @barbosadantasvpj So you question is how should you handle empty TextInputs when making calculations…correct? Are you just adding the grades ( in which case it’s ok to substitute in a 0) or do you also need to average the grades (in which case there’s a need to exclude the empty grades) ? Thanks ---
