I have two textboxes in my form. (W and H)
values are numbers and 75cm<W<750cm and 75cm<H<180cm
can you please help and guide me
how I can change the textbox value with Radio Buttons and convert them to mm?!
and as you know The allowable range of numbers must also be changed.
In this scenario, I recommend putting the radio buttons first, to offer the choice of cm or mm. Then you would have four fields, W in mm and W in cm, plus H in mm and H in cm. You would show the correct pair of fields based on the radio button selection that was made. Only one W and one H field would ever be shown. Would that work for you?
