Chatsetattr issue

I'm trying to make a macro for the spell Mass Healing Word in 5e with chatsetattr.  I know my problem is somewhere in the query.  I think I need to do something with some commas or a close bracket but I don't know what.   ``` !modbattr --charid @{target|target 1|character_id}, @{target|target 2|character_id}, @{target|target 3|character_id}, @{target|target 4|character_id}, @{target|target 5|character_id}, @{target|target 6|character_id} --hp|?{What level?|Level 3, +[[1d4+5]]|Level 4, +[[2d4+6]]|Level 5, +[[3d4+7]]} --fb-from @{selected|character_name} --fb-public --fb-header Mass Cure Wounds --fb-content Robert heals _CHARNAME_ for _TCUR0_ hitpoints. ```

Do you need commas between the charids? I'd strip out all the fb commands, and restructure the query, for testing purposes. Something like: !modbattr --charid @{target|target 1|character_id} @{target|target 2|character_id} @{target|target 3|character_id} @{target|target 4|character_id} @{target|target 5|character_id} @{target|target 6|character_id} --hp|+[[?{What level?|Level 3,1d4+5|Level 4,2d4+6|Level 5,+3d4+7}]]  And see if that works.
