Trying to make these blink

@overlay 5241241332875264_HEARTS1 opacity 1 in 0 THEN overlay 5241241332875264_HEARTS1 opacity 0.5 in 2 THEN overlay 5241241332875264_HEARTS1 opacity 1 in 2 loop INFINITE times

2

&overlay HEARTS1 opacity 1 in 0
&overlay HEARTS1 opacity 0.5 in 2 THEN overlay HEARTS1 opacity 1 in 2 loop INFINITE times

Never use the @ sign with looping overlays, always use &

Ok! Thank you so much! :blush:
