No$GBA Break if "022B7760" R1 < 90. All I get is "huh?" errors

[gukingofheart]

I know how to do a normal write breakpoint
[022B7760]!
But all I get are errors whenever I want it to break for some conditions.

I tried the $ but since the site gives no examples on exactly what to write, I get errors... and I tried different combinations.
