    [RESOLVED] Adding Numbers Together (you won't believe this)

    Normally, if you have numbers in text boxes you can say

    TextBox3.text = STR( val(textbox1.text) + val(textbox2.text))
    eg, 5 = 2 + 3

    This has been the old faithful simple addition for as long as I can remember

    I have suddenly found this does not work, if the text box contains a formatted value - namely

    When Textbox1 contains 1,000
    Textbox2 contains 2,000

    The answer becomes 3 (NOT 3000)

    Is there a simple way to deal with this problem, without running REPLACE, for example

    PS Why do I have to scroll the screen across to find the SUBMIT NEW THREAD Button
    (Is it my browser IE8)

    Convert to decimal, or don't allow anything but numbers

    Got it

    I should use CCur instead of Val

    TextBox3.text = STR( CCur(textbox1.text) + CCur(textbox2.text))

    (where have the formatting controls for the forum gone)

    I would also advise using CStr() rather than the old STR() function

    CStr() will not add the leading space that STR() places in there.

    Val() is dangerous in many cases, it reads the value left to right and stops when it finds a non numeric character

    24ZY3 would return 24 if val was used on it even though the string is not a valid number at all.
