Hi @user412
This might be due to a number of reasons. My suspicion is that the your snippets folder is not "connected".
Let me explain.
Some commands in Text Blaze (specifically those that can read from websites or write to them, such as urlsend) need to be in a "connected folder".
Please try clicking on the folder that contains this particular snippet.
At the bottom right, you'll see something like this:

Click on "Configure" and then allow the permissions.
If this doesn't solve the issue, please drop us an email at support@blaze.today so we can have a closer look.
