Illiad vs. VB6.0 (who's retarded?)

[Illiad]

I don't get this at all! I'm making a program that "Locks" windows for a defined period of time. I have 3 settings. Setting 1 is to lockdown for a certain ammount of time. Setting 2 is to lock permanently. Setting 3 is to restart once the timer is completed. That's where the problem is! In setting 3's Subroutine...
Heres a fragment of the code...

Private Sub Timer1_Timer()
BlockInput True
If lbltime.Caption > 0 Then
    lbltime.Caption = lbltime.Caption - 1
Else
    lbltime.Enabled = False
    BlockInput False
    Sleep 800
    Unload frmLocked
    Unload frmWinLock
    Timer1.Enabled = False
    End
End If
End Sub
Private Sub Timer2_Timer()
BlockInput True
lbltime.Caption = "++++"
If lbltime.ForeColor = &H80000012 Then
    lbltime.ForeColor = &HE0E0E0
Else
    lbltime.ForeColor = &H80000012
End If
End Sub
Private Sub Timer3_Timer()
BlockInput True
If lbltime.Caption > 0 Then
    lbltime.Caption = lbltime.Caption - 1
Else
    lbltime.Enabled = False
    BlockInput False
    Sleep 800
    Unload frmLocked
    Unload frmWinLock
    Timer1.Enabled = False
    End
End If
End Sub

The settings are represented by timers (e.g. setting 1 is timer1 and so on)
Whenver I run the program on setting 3 I get this error message "Runtime Error Type 13, Type Mismatch" on the "If lbltime.Caption > 0 Then" line on timer3. However, as you may see above, the code for timer1 and timer3 are the same. I know that timer3 won't restart windows cauz I havent augmented its code yet. But VB only gets the error on timer3...whats going on?!

Note: lbltime.caption is set by a variable "seconds", "seconds" is a public integer.
