L.S. I try to remove empty place in a list. I want to make user friendly input and need a amount of strings 1 to 4. If there is a blank Dynamo crash. I try a lot but noop result yet. I hoop to get a good direction for a solution. Greeting Jan-Willem [image]

check this out: https://dictionary.dynamobim.com/2/#/List/Modify/Action/ReplaceByCondition use the conditon == “”;

and your string is not an “Space”, but it is completely empty use this “”; instead of " ";
