Hello - This is regarding Thunkable and Firebase In the image you can see that i upload in blue - information around a specific date and time. And i Assume now the list includes thousands of records Have two related questions. Is there a possibility to loop the keys to… 1. Get the value from keys which contains “Datum: 30” only? 2. Delete the whole key/value if number is below 30? ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/2/f/2fc7a5668c7b01669a96dad779a17dae7fef17f9.png) ---

Hi @stefansladdeneng1 You will need to use a loop that runs for each item in the list “problem” and inside have two conditions using the [“get object properties of”](https://docs.thunkable.com/blocks/blocks/objects#get-object-properties-of) and [“get substring”](https://docs.thunkable.com/blocks/blocks/text#get-substring) blocks
