Mekkablue - new tab with small paths script error/not working

Version 2.6 (1192)

When using mekkablue’s - new tab with small paths (With delete paths right away ticked), I am getting the following error in the macro window:

‘‘Find Small Paths Error: could not convert string to float:’’

You need to input a number in both entry fields.

Update: I made the script more failsafe and tell you what is wrong.
