Condition Sentence for Nested multiple Embeddable Link Field

Question

I'm trying to implement Condition Sentence for nested multiple embeddable link field in the DW Tempate.

But in the 1st Repeat sentence, I can't judge if the 2nd embeddable link field is empty or not.

could you give me any ideas for this?

Thank you very much in advance.

My code is below

<!-- TemplateBeginRepeat name="Component.Fields.Embeddable_Block_Items" -->

<!-- TemplateBeginIf cond="Field.Embeddable_Image_Link_Items != '' || Field.Description != ''" -->
<!-- TemplateBeginIf cond="Field.Description != ''" -->
This should be worked.
<!-- TemplateEndIf -->

<!-- TemplateBeginRepeat  name="Field.Embeddable_Image_Link_Items" -->
This should worked ${TemplateRepeatIndex}
<!-- TemplateEndRepeat -->
<!-- TemplateEndIf -->
<!-- TemplateEndRepeat -->

How to handle nested repeating regions has been explained by Frank van Puffelen on Stack Overflow before here: How to handle nested repeating regions in Dreamweaver TBBs

Most of the time the trick is in knowing what variables to use where. There are a couple of crucial variables that can help you here, being: Field, FieldPath and TemplateRepeatIndex. You can simply add the following fragment in your DWT (inside every TemplateBeginRepeat) while you are building/debugging your Template.

(FieldPath=@@FieldPath@@, TemplateRepeatIndex=@@TemplateRepeatIndex@@)

Also note that when nesting repeating regions, there is only one TemplateRepeatIndex, that of the current region you are in. More on that topic can also be found on Tridion Practice - Iterate over multi-value multi-level embedded fields in DWT

I'll assume "Embeddable_Image_Link_Items" is a multivalue embedded field? In that case you cannot directly test if the field has content in a DWT.

Your can either use a "hack" in the DWT to assess if the field has any content by using a template repeat region:
<!-- TemplateBeginRepeat name="Field.Embeddable_Image_Link_Items" -->
<!-- TemplateBeginIf cond="TemplateRepeatIndex = 0" -->
Field has value (one or more)
<!-- TemplateEndIf -->
<!-- TemplateEndRepeat -->

Or if your multivalue embedded field has mandatory subfields you can use
<!-- TemplateBeginIf cond="Field.Embeddable_Image_Link_Items.subfield" -->
<!-- TemplateEndIf -->
which will evaluate to true if any of the embedded fields have a value for "subfield".

Or you need to create a C# fragment or assembly TBB to determine if the field has value and push this into a separate package variable which you evaluate in your DWT.
<!-- TemplateBeginIf cond="Embeddable_Image_Link_Items_HasValues" -->
Field has value (one or more)
<!-- TemplateEndIf -->
