button for multiple instantaneous spells

[scyllel]

Literally, it just doesn't seem to progress; its as if I tried to cast a targeted spell with no target. I push the macro button and nothing happens.

macro looks like this:

/target_self
spell:"Radiance" (has a casting time of instant) Primary [x] Target {blank}
/target_self
spell:"Salvation" Primary [ ] Target {blank}
/target_previous

Radiance fires off on self, but nothing queues up, nothing else fires. I think there is some time that must pass between casts, even if the first spell is "instant". I need to figure out how to insert a pause.
