Visual Basic If Statement help

I am doing a project and i have a scroll bar that has QBColors on it as you go 1 - 15 it displays the colors in the picture box. it also has a text box to enter 1 - 15 to go to that QBColor. I was wondering how to make it so that if a value greater than 15 is entered into the text box to prompt the user and just stay at the max, 15.

if textbox1.text > 15 then msgbox "Please enter a digit between 1-15"

you might also want to do it so if they enter a value less than 1.

if textbox1.text < 1 then msgbox "Please enter a digit between 1-15"

i think these will help, but if they don't just say so, because it's been awile for me, so i might have made a mistake.

You may also want to make sure that what they enter in the Textbox is actually a number before trying to use it as one.

Slap some Val() functions into Tylor's statement would work perfectly. Here is an example that does not use a msgbox (in general using msgboxs is bad programming practice).
Dim lastValue As Integer
Private Sub Form_Load()
lastValue = 1
Text1.Text = lastValue
End Sub
Private Sub Command1_click()
If Val(Text1.Text) < 1 Or Val(Text1.Text) > 15 Then
Text1.Text = lastValue
Text1.SetFocus
Text1.SelStart = 0
Text1.SelLength = Len(Text1.Text)
Else
lastValue = Text1.Text
End If
End Sub

In this code I check to see if the value of the text is valid, and if is invalid I change it back to the last valid entry and highlight it.
