Ran through the troubleshooting steps [here](https://resources.sienci.com/view/gs-gsender-grbl-alarm-error-codes/#error-1-2-20-24-26-28). I dont think its any of those. It has to do with trying to use variables. I tried to follow the macro guide [here](https://resources.sienci.com/view/gs-macros/) and I am not sure where I am going wrong. I have a Shapeoko 5 Pro. If I just enter in the number and delete the variable it works just fine.

Trying to run this:

%hello = 10  
G91 G0 X[%hello]

outputs this in console:

G91 G0 X[%hello]

Bad number format

What am I doing wrong here?

% defines the variable - using it you just add the name.

So it should be

```auto

%hello = 10
G91 G0 X[hello]

```
