Minimum length of input text

I want to make a check to see if the input is more than 3 characters but I can’t find a code block that helps me do that.
Here I am looking to se if the text is empty but it is not working. Instead I would like to be able to change the parameter later to check for a string length of 2, 3 or 4 characters. Any idea of where I should find the block?

Hi,

You could use something like the below, which checks, if the value is 3 or more in length. Just adjust the clause as required.
