AMPScript - Only Show RSS Items from Last 14 Days

Question

When I try to use the below code, I'm not able to see a preview email; it just says there's an error in the email.

%%[

Var @xml, @titles, @title, @links, @link, @descs, @desc, @dates, @date, @cnt 

Set @xml = ContentArea("3618") 

Set @titles =
BuildRowsetFromXML(@xml,"//item/title",1) 
Set @links =
BuildRowsetFromXML(@xml,"//item/link",1) 
Set @descs =
BuildRowsetFromXML(@xml,"//item/description",1) 
Set @dates =
BuildRowsetFromXML(@xml,"//item/pubDate",1)


SET @rows = RowCount(@titles)
Set @date = Field(Row(@dates,@cnt), "Value")

IF @rows >= 1 THEN

    for @cnt = 1 to @rows do

        IF DateDiff(NOW(),@date, "D") <= 14 THEN


    for @cnt = 1 to @rows do 
        Set @title = Field(Row(@titles,@cnt), "Value") 
        Set @link = Field(Row(@links,@cnt), "Value") 
Set @desc = Field(Row(@descs,@cnt), "Value") ]%%


<h1><a title="%%=v(@title)=%%" alias="%%=v(@title)=%%"
href="%%=v(@link)=%%">%%=v(@title)=%%</a></h1>
<p>%%=v(@desc)=%% <br />%%=v(@date)=%%</p> </div>


%%[ 
        ENDIF
    NEXT @cnt 
ENDIF
]%%

Content Area 3618 is where I'm pulling in my RSS:

%%httpget; 0 "RSS FEED I'm USING"%%

Looks like you've got an extra FOR loop. Maybe something like this is what you intended:

%%[

Var @xml, @titles, @title, @links, @link, @descs, @desc, @dates, @date, @cnt 

Set @xml = ContentArea("3618") 

Set @titles = BuildRowsetFromXML(@xml,"//item/title",1) 
Set @links = BuildRowsetFromXML(@xml,"//item/link",1) 
Set @descs = BuildRowsetFromXML(@xml,"//item/description",1) 
Set @dates = BuildRowsetFromXML(@xml,"//item/pubDate",1)

SET @rows = RowCount(@titles)

IF @rows >= 1 THEN

    for @cnt = 1 to @rows do

        Set @date = Field(Row(@dates,@cnt), "Value")

        IF DateDiff(NOW(),@date, "D") <= 14 THEN

            Set @title = Field(Row(@titles,@cnt), "Value") 
            Set @link = Field(Row(@links,@cnt), "Value") 
            Set @desc = Field(Row(@descs,@cnt), "Value") 

            ]%%

            <h1><a title="%%=v(@title)=%%" alias="%%=v(@title)=%%" href="%%=v(@link)=%%">%%=v(@title)=%%</a></h1>
            <p>
                %%=v(@desc)=%% 
                <br />%%=v(@date)=%%
            </p>

            %%[ 
        ENDIF

    NEXT @cnt

ENDIF
]%%
