I'm pretty new to skript, i have an issue that essentially boils down to this. I don't seem to be able to use variables in blockdata. Here's my skript, am i doing something wrong?
```
command /ametest:
trigger:
set {_a} to "south"
set block at player's location to amethyst_cluster[facing={_a}]
```
```
command /ametest:
trigger:
set {_a} to "south"
set block at player's location to amethyst_cluster[facing={_a}]
```
