The community member is having trouble using a variable in their HTTP request, and they want to use it as {{instance}} and change the value as needed. The other community members try to help by asking for more details, such as steps to reproduce the issue, what's happening, and what the community member was expecting. One community member suggests using the "Variable values for test" section to replace the variable with a value for testing. However, the original community member still seems to be having trouble and requests an example or a video to help them understand how to do it correctly.
