Help with VBA issue, mysterious to me

[TomCon]

PLEASE IGNORE...THE PROBLEM IS SOLVED (TYPO)...Sorry!
Here is VBA:

Sub tst_axis()
Dim MinChrt As Double
Dim MaxChrt As Double
    Sheets("c.Wt").Select
    ActiveSheet.ChartObjects("Chart 1").Activate
    MinChrt = Application.WorksheetFunction.Floor(Application.WorksheetFunction.Min([ChWt_InstWt.Y]), 1)
    MaxChrt = Application.WorksheetFunction.Ceiling(Application.WorksheetFunction.Max([ChWt_InstWt.Y]), 1)
    ActiveChart.Axes(xlValue).MinimumScale = 174
    ActiveChart.Axes(xlValue).MaximumScale = 184
    ActiveChart.Axes(xlValue).MinumumScale = MinChrt
    ActiveChart.Axes(xlValue).MaximumScale = MaxChrt
End Sub

The following two statements from above execute without error

    ActiveChart.Axes(xlValue).MinimumScale = 174
    ActiveChart.Axes(xlValue).MaximumScale = 184

However, the following statements [from above] give "Runtime error 438, object doesn't support this property or method"

    ActiveChart.Axes(xlValue).MinumumScale = MinChrt
    ActiveChart.Axes(xlValue).MaximumScale = MaxChrt

In the immediate window, the variables MinChrt and MaxChrt give the same values as in the code, 174 and 184

?MinChrt
 174
?MaxChrt
 184

Any idea what is going on, or how i can set these Axis properties to a variable value that is computed by the code?

Thanks!
