Making text input required, and enforcing that at least one checkbox is checked based on answer

 

I have a document where a home seller is answering questions about the condition of their property. I'm trying to accomplish the following:

- If a seller chooses yes when answering if their property has defects, they need to fill out at least one checkbox describing the type of defect. How can I enforce this? Also, I currently has this as a radiogroup. Will this allow someone to choose multiple options? If not, how would I set this up?

- If a seller chooses yes when answering if their property has defects, how can I enforce that they fill out a text input?

 

Sample text:

 

Are you (Seller) aware of any significant defects/malfunctions in any of the following? {{*esl_optionA:Signer1:Radio:Group("HasDefects"),Value(""),size(10,10),offset(40,-8)}} Yes          

{{*esl_optionB:Signer1:Radio:Group("HasDefects"),Value(""),size(10,10),offset(40,-8)}}  No

 

If yes, check appropriate space(s) below.  (Question 1: How can I enforce that if HasDefects option A is chosen that at least one of the following checkboxes are required? Note that someone could fill out more than one checkbox)

 

{{esl_optionA:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Interior

{{esl_optionB:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Walls

{{esl_optionC:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}}Ceilings 

{{esl_optionD:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Floors

{{esl_optionE:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Exterior Walls 

{{esl_optionF:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Insulation

{{esl_optionG:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Roof(s)

{{esl_optionH:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Windows

{{esl_optionI:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Doors 

{{esl_optionJ:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} FoundationSlab(s)

{{esl_optionK:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Driveways

{{esl_optionL:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Sidewalks

{{esl_optionM:Signer1:Radio:Group("DefectType"),Value(""),size(10,10),offset(40,-8)}} Walls/Fences

 

If any of the above is checked, explain.

{{esl:Signer1:textfield:size(40,15),Maxlen(200)}}

(Question 2: How can I make this text input required if the HasDefects Option A is chosen?)
