Checkbox State Defined in Macro

I want to define the state of a checkbox based on an If/Then test in a macro.
If Sheets("Rnd " & RoundsFlown - 1 & "").Range("X49") > 0 Then
Checkbox14 = True

The statement in this macro has no effect. The command "Checkbox14 = True" works fine when the command is contained within the code defining the function of other checkboxes.

I have tested the functionality of the command within a macro by writing a very simple macro consisting of nothing more than "Checkbox 14 = True" which the running of also has no effect.

Please tell me what I am missing.

AlphaFrog, thanks.
That was too easy. I'll try to come up with a harder one next time.

I just needed to tell Excel what sheet to invoke the macro.
Seems odd to me that Excel needed that specific direction since all the rest of the macro commands are invoked in the active sheet.

Ultimately I used "ActiveSheet.Checkbox14 = True" (Do you think there is any problem leaving off the ".Value" portion of the code?)
