I am trying to limit an input field in a web form created through business catalyst

I used <input type="text" maxlength="255" size="30"> but it did not work....

Nothing to do with BC that is straight HTML, assuming the rest your HTML is valid, you want to limit the input to 255 characters there is nothing there that would not allow that (cept really really old browsers)
