    right..after many hours pulling my hair out..i have the following problem concerning an input box and looping..

    the prob is as follows:

    i have a text box where the user must enter a telephone number, if s/he enters it wrong 3 times then the form resets..so , i check the value in the textbox using the IsNumeric function and using an if...then statement i begin the loop..however if i enter a non numeric , which results in a message box popping up and notifying the user that the date must be numeric..then if i enter numeric data into the input box the data enters the textbox but the input box pops up again..and again and again until the loop finishes and resets the form...

    :(
    as i said i really have tried everything with this..

    any help, even minimal would be greatly appreciated,

    thanks

    You're probably overcomplicating your nested loop logic. Keep it as simple as possible. Something like:
    Private Sub Command1_Click()
        Static iAttempt As Integer
        
        If IsNumeric(Text1.Text) Then
            'Number is Valid - Do Stuff
        Else
            iAttempt = iAttempt + 1
            MsgBox "Numeric value needed!"
        End If
        
        If iAttempt = 3 Then
            iAttempt = 0
            'Reset after 3 attemps - Do Stuff
        End If
    End Sub

    right... but if the value in the inputbox is true how do i write the code so this value is stored in the property of the textbox

    is it...
    dim intAtempt as integer

    for intAttempt = 0 to 2

    if isNumeric(txtNumber.text) = true then
    txtNumber.text = inputbox.text (i know this is wrong but i dont know what to do)
    else
    msgbox "Data must be numeric" , vbExclamation, "Incorrect Data"
    txtNumber.text = " "

    end if

    Next intAttempt


    is this correct apart from the issue concerning the inputbox?
    thanks
