Populate image with link using Velocity script

Anyone knows why the below script fails to populate an email with an image that has a URL?

<p style="text-align: center;"><a href="${contentUrl_1}?{{my.programUTM}}" target="_blank"><img src="${contentImageUrl_1}" alt="${contentImageText_1}" height="${contentImageHeight_1}" width="${contentImageWidth_1}" /></a><br /></p>


If I replace the 'href' section with something else than the image appears but the link will not work as the URL is not valid (see below).

<p style="text-align: center;"><a href="{{my.Content2_Link}}" target="_blank"><img src="${contentImageUrl_2}" alt="${contentImageText_2}" height="${contentImageHeight_2}" width="${contentImageWidth_2}" /></a><br /></p>

The URL used in the first version also works if used in a text.

href="${contentUrl_1}?{{my.programUTM}}"

If I replace the URL with a valid but short URL (e.g. yahoo.com) than the link works but the image disappears (and all other velocity tokens in the same email tile also fail).

Any suggestions?

Can't be the whole of the current script, or else you're setting vars like $contentUrl_1 in another script. Either way, we're not seeing the whole thing.

At least part of the problem is that it looks like you're trying to interpolate a text {{my.token}} in the VTL context. That won't work. Depending on how you test, you may get totally borked HTML sometimes and visible-but-still-not-working links at other times. But you aren't going to get the output you want.

Instead of including a text {{my.token}}, create another Velocity {{my.token}} and have it set a $variable to the UTM query string (this token it doesn't output anything at all, it only #set()s the var). Include this non-output {{my.token}} at the top of the email. Then you can Include that $variable in subsequent Velocity {{my.tokens}}.  For an example of the way variable scope is preserved ("context chaining") between Velocity tokens, see my blog post http://blog.teknkl.com/just-in-time-content-suppression-with-a-comment-token/​.

You'll have to provide the full HTML output/s (and the full Velocity code) for further troubleshooting.
