Hi ocorbo, welcome to Thunkable! 🎉

Be sure to check out [How to ask Great Questions v2.0](https://community.thunkable.com/t/how-to-ask-great-questions-v2-0/2689983/1), the [Community Guidelines](https://community.thunkable.com/t/community-guidelines/78/8), and our [Getting Started Guide](https://docs.thunkable.com/getting-started/get-started) to make the best of your Thunkable Community experience!

As for your question, there are a few areas that need to be corrected.

You have “set app variable app variable BluetoohDevicesNameList” after your scan. There is a dedicated [“set variable” block](https://docs.thunkable.com/blocks/blocks/variables-overview/variables#set-variable-to) you should use instead. You might have to click on the dropdown and select the variable you want to set.

You need [loop](https://docs.thunkable.com/blocks/blocks/control#for-each-item-j-in-list) through the app variable BluetoothDevicesNameList and if “j” contains “pdstal”, then you do what you need to with “j” as it contains the name you are looking for.
