To implement a backspace, you would have to write your own javascript function to subtract off the last character of the string. Lectora will do string subtraction, but you have to know what to subtract.For instance, if you have the string "cataract" you could subtract "t" and get "catarac" ... but you have to know the "t".If you are dealing with numbers, Lectora tests the strings to see if they are numbers and does addition not string addition. For instance, if you set a variable to "125" and then add "5" ... the result will be "130" not "1255".If you had a string "125" and added "a" to it you would get "125a".TimTim
