Marketo Velocity Script Error While Changing CTA Link Based on Lead Country

Question

Hi everyone,I have a requirement where the email content remains the same, but the CTA link needs to change dynamically based on the lead's country using a Velocity Script in Marketo.However, I'm getting an error when I deploy the campaign.Requirement:Same email template for all recipients. Change only the CTA URL based on the lead's country. Example: US → www.youtube.com Canada → https://example.com/ca India → https://example.com/in Behavior:✅ Email Preview: Works as expected. ❌ Smart Campaign Send: Fails with a Velocity Script error.Velocity Script:#set($country = ${lead.Country})#set($url = "www.google.com")#if($country == "India") #set($url = "example.com/in")#elseif($country == "United States") #set($url = "www.youtube.com ")#elseif($country == "Canada") #set($url = "example.com/ca")#else #set($url = "www.google.com")#end${url}HTML:

${CtaText}

Error: Has anyone encountered this issue before? Am I missing something in the Velocity syntax, or is there a better approach for dynamically changing CTA links based on the lead's country?Any help or suggestions would be greatly appreciated. Thank you!

@Ram_SaiDa,I tested your implementation and was able to reproduce the behavior.The Velocity script itself is fine for resolving the URL based on the lead's country. However, the issue is that the script is only returning the URL, and you're then using that Velocity token inside the href attribute:While this correctly resolves the destination URL, however, this approach causing issues with Marketo's link tracking.What worked for me was generating the complete tag within the Velocity script instead of returning only the URL. Then, in the email, I simply rendered the Velocity token directly rather than wrapping it inside another tag.#set($country = ${lead.Country})#set($url = "google.com")#if($country == "India") #set($url = "example.com/in")#elseif($country == "United States") #set($url = "youtube.com ")#elseif($country == "Canada") #set($url = "example.com/ca")#else #set($url = "google.com")#end CTA ButtonAfter testing with multiple country values (US, Canada, and India), the CTA resolved to the correct destination for each recipient, and Marketo click tracking also worked as expected.I'd recommend trying that approach if your goal is to have both dynamic URLs and reliable click tracking.I'd recommend using Dynamic Content feature to personalize the CTA link based on the recipient's country instead of velocity script.

If you’re deliberately untracking a link instead of fixing the code, you should at least add

mkt_tok=${mktmail.MKT_TOK}

to the query string so you don’t lose cookie association.

Also @Ram_SaiDa please ensure you use the Insert Code function here on the community so your code is readable.

Issue	Fix
Invalid variable assignment syntax	Use `$lead.Country` instead of `${lead.Country}` inside `#set`
Bad URL output	Remove trailing spaces and include full `https://` URLs
Token mismatch	Make sure `{{my.urlcountry}}` is the actual Email Script Token name
Link tracking/resolution issues	Use fully formed URLs or `class="mktNoTrack"` if needed
