Validate A Var

[Shadow3641]

Is there a way to ensure the user has inputted a number in a dialog box? So far i have came up with this but no matter what i put in it says its good.

Code: Select all

  object MSMemo5: tMSMemo
    Left = 16
    Top = 344
    Width = 241
    Height = 21
    Hint = 'Put in how many weeks it will take to be delivered.'
    Text = 'Delivery Date In Weeks'
    TabOrder = 5
  end

Code: Select all

GetDialogProperty>Dialog2,MSMemo5,Text,deliveryDate

Code: Select all

  If>%deliveryDate%>0
  Else
    MessageModal>Please ensure Delivery Date is correct.
    Let>break=1
  Endif

Thanks for the help

Never mind I found a way to do it with the Format
Had to add in

Code: Select all

Format>%d,deliveryDate,result

with this any letter or special char in the string will put the value to a 0
