Scripting URL Link to Top Frame

Scripting URL Link to Top Frame

Hey, my HTML view form is working nicely except for a link issue I've been unable to fix - a pesky html link that forces open a new window. The table below calls the variable "BlogLink" into a table cell, creating a list of blog pages on wine (sorted by rating) with links to the individual blog pages for each wine. On the blog, since these links are in a iFrame, they force open a new window, frustrating for visitors. Is there a way to fix this with scripting? I have tried the instructions at the Open URL help center page here:
https://help.creator.zoho.com/Open-URL.html
 
These instructions don't work for me. I don't know how to make the script pick up the BlogLink field. Would love some help, as specific as possible since I'm very new at this.
 
PS - It sure would be nice if in the form menu we could select an option for a link to open in _top, and not just new or same, which are the only two options at present. Seems like that could fix it.
