Your code directly in the edit box above, there are three drop-down box, you figure for the open position, whether there Label4 look at this object, if not, should you put the Label name, or does not exist the Label on this form

CodePudding user response:

Your control of the name is well, the text attributes and there is no automatic transform to capitalize the first letter, may be control selection problems
