Dan’s references are indispensable… However the simple answer is your code currently set first three items of the array of defaults to numbers, or more exactly ‘integers’ [e.g. 100]. So even if the user tryies to enter a ‘float’, it will probably fail [e.g. 100.5 (or 100,5 if their locale uses a , …

…And that is why, as I have already explained, in that particular use - related to the user INPUTbox - it can take a comma within a float-input - but only in the right locale. AND of course, as I explained in the very nest paragraph - in the Ruby API the decimal-separator must ALWAYS be the ‘.’ !

When using the UI.inputbox whatever class you provide in the default values it will try to convert he user input back into that value. So if you are working with units (Lengths), then make sure the default is a Length prompts = ['Name', 'Width', 'Height'] defaults = ['My Own Square', 5.m, 2.m] inp…

Thank you very much for your help… Joseph.
