total rolled max 30, total rolled min 1, is this possible?

Hello script gods, Is there a command or way already developed for a total roll including modifiers such as + str bonus to never go above 30 or under 1? To be clear, a macro such as [[1d20 + @{Selected|Ability-Mod} + @{Selected|PB} ]] never giving a result above 30 or below 1.   Not a super high need, but against hugely powerful foes, or ones with crazy negitives, it would be great to see the rolls confined to the max and min of the allowed rolled totals of the 5e game.  Thanks! Barry

Could do on or the other with kh/kl. [[{1d20 + @{Selected|Ability-Mod} + @{Selected|PB},30d1}kl]] Or [[{1d20 + @{Selected|Ability-Mod} + @{Selected|PB},1d1}kh]] Could maybe combine them as: [[{{1d20 + @{Selected|Ability-Mod} + @{Selected|PB},30d1}kl,1d1}kh]] I'm on my phone, so I can't test it. EDIT: may need to add some nested inline rolls in there

Thank you for the suggestion Scott C.  I do get a "SyntaxError: Expected [0-9] but end of input found" for each of the script suggestions though.

Try this: [[ {{1d20 + @{Selected|Ability-Mod} + @{Selected|PB}, 1 + 0d0}kh1, 30 + 0d0}kl1 ]]

Thank you Silvyre! Works perfectly. =D
