Add an FX to a Macro

I am using a potion of healing macro that updates HP.  I have it working but I would like to add an FX to this as well.  Any way I can do it by adding a script?  To make it simple I would use /fx burn-holy This is the Potion of Healing script I have working already !token-mod {{   --set     bar1_value|+?{Potion|Regular,[[2d4+2]]|Greater,[[4d4+4]]|Superior,[[8d4+8]]|Supreme,[[10d4+20]]}!   --report     all|"{name} drinks a healing potion and recovers {bar1_value:abschange} HP. " }}

I'd just tack the fx command on the macro after the fact.  Example:  !token-mod {{ stuff }} /fx command (note: I am being lazy and not typing the contents of "stuff" and "command".)

Gauss I did that but the FX command seems to override the token mod script.

Could you post the macro of that?

!token-mod {{   --set     bar1_value|+?{Potion|Regular,[[2d4+2]]|Greater,[[4d4+4]]|Superior,[[8d4+8]]|Supreme,[[10d4+20]]}!   --report     all|"{name} drinks a healing potion and recovers {bar1_value:abschange} HP. " }} /fx glow-charm @{target|token_id} @{selected|token_id}

Here you go:  !token-mod {{ --ids @{target|Target 1|token_id} --set bar1_value|+?{Potion|Regular,[[2d4+2]]|Greater,[[4d4+4]]|Superior,[[8d4+8]]|Supreme,[[10d4+20]]}! --report all|"{name} drinks a healing potion and recovers {bar1_value:abschange} HP. " }} /fx glow-charm @{target|Target 1|token_id}

thank you Gauss

To explain what is going on, here: There's a long standing bug (so long standing that it's just the way things operate on Roll20) that messages with a targeting structure (i.e., @{target|token_id} ) do not have "selected" tokens. So a script like TokenMod, which is defaulted to operate on the selected tokens, has nothing to do when you introduce a targeting statement without further alterations. And, for a multi-command macro, the whole thing is essentially treated as one big message for the purposes of designating any selected tokens... if one of the statements has a targeting command, none of the statements will have selected tokens. Gauss gets around that by using the "--ids" argument of TokenMod, which allows you to explicitly designate the tokens it should affect. (The Metascript Toolbox has ways to give selected tokens to a message, if you had to get around this "bug" in a script/message that did not otherwise offer something like an "--ids" argument option.)
