Excel VBA: Use Checkbox Value When Command Button Entered

I'm trying to teach myself VBA by programming one of those old 'Choose Your Own Adventure' books in Excel (just for my own fun, not to sell). I have a sheet with a single ActiveX Checkbox ("chkTakeCoins") and a separate command button. These are not in a Userform, they're just on the sheet. I can't figure out how to write the Command Button code to see if chkTakeCoins is true or false. Do I need to Call the chkTakeCoins checkbox from the command button code? As it's written below I get an 'Object required' error.

    Sub btn5to147_Click()
        If chkTakeCoins.Value = True Then
             Sheets("Inventory").Range("coins") = 1
        Else
             Sheets("Inventory").Range("coins") = 0
        End If
        Worksheets("147").Activate
    End Sub

Help appreciated.
