I have a User form with (20) option buttons on it. It does what I want by
only being able to check 1 option button.

Option Button Names:
OB_601
OB_602 - OB_619
OB_620

What I need help with is when user checks the correct option button, that
button exicutes code located in a module.

Code in Module: There are (20) Subs named like below
Sub String_01()
Sub String_02() - Sub String_19()
Sub String_20()

I think the code for each Option button is something like this, because
there default position is False and they only show true when selected.

If OB_601 = True
then call Sub String_01()
If OB_602 = True
then call Sub String_02()
If OB_603 = True
then call Sub String_03()

Etc....
End Sub
