Validation: Multiple Sets Of Different Controls

I already have validation code to test TextBoxes for numeric values as well as the size of the numeric on a MultiPage userform. Of these 65 TextBoxes, 40 are within frames associated with two OptionButtons. Once the following conditions occur:

1) the frame’s focus is lost;
2) the textbox value is not null;
3) And the two Option Buttons’ values are both false,

I want a UserForm to load informing user that the OptionButtons must be selected. In addition, there are three different user messages one of which will be associated with one of the forty TextBoxes. The Names of the TextBoxes and their cognate pair of OptionButtons will share the same prefix, i.e., ***_Text, ***_Opt1, ***_Opt2 and the OptionButtuns Tags are labeled so as their values will get associated with the correct member of the three different messages. Along with displaying the appropriate message contained within this validating UserForm, I’d like to have the appropriate pair of Option Buttons whose selected Value gets passed to the correct option button on the main MultiPage form. The user cannot continue unless one of the OptionButtons is selected. How best is this accomplished? Should I also have the TextBox’s Tag set to a value matching its associated pair of OptionButtons? Whilst I could code this action at the time of Value submission, I’ve decided validate on the MultiPage user form rather than at the Value submission although I’m not married to this
