i blame my severe cold and lack of sleep for the lapse in common sense so please someone tell me what i’m doing wrong. basically im trying to write a quick function that takes all of our door numbers and renumbers them based on +100; i.e. door 025 would become door 125. instead of the ground floor starting at 000 they want it to start at 100, so essentially all door numbers get increased by 100. instead of the math battery actually adding the values together it just combines them to a single value; i.e. 010 + 100 = 010100 when it should equal 110.

# Adding math array

Thanks for the reply Vikram. I did use the string to number node originally but the resulting value was throwing an error in the element.set parameter.by name. Converting that value back to a string seemed to do the trick.
