MsgBox With Dynamic Message

My code has a number of tests for 5 variables of type Boolean.

if after the code has run the five variables look like this:

Code:
variable1 = False
variable2 = False
variable3 = True
variable4 = True
variable5 = True

I want a message box to be displayed with text for the variables that return a True value. So my message box for the above example would read:

Code:
variable3 text
variable4 text
variable5 text

If, however, the next time the code runs the five variables look like this:

Code:
variable1 = True
variable2 = False
variable3 = True
variable4 = False
variable5 = False

The message box should look like this:

Code:
variable1 text
variable3 text

Is there a simple way to do something like this?
