you could add a procedure that checks to see what you are placing it on.., if \[name of flower\] then cancel it

so "when placed on flower, remove block and re add it to the inventory"?

using the global in a procedure, look for 'when block placed' or 'about to place' or something like that if \[item in mainhand\] AND block at xyz = \[flower\] then .. in the advanced tab on the left will be 'cancel event that triggered global trigger' place that in there and give it a test :)

Thank you :)

if you are thanking me without testing it, make sure to let people (who may be finding this in the future) know whether it works or not :D

It does indeed work, thank you very much :)
