if then statement in email for deal property

I am using the edit HTML module in an email (not an email template) and trying to get the following bit of code to work:
{% if deal.deal_currency_code == ‘USD’ %}<p>usd text</p>{% else %}<p>non-usd text</p>{% endif %}

I am previewing it with the currency code property above it so that I can compare, but it only shows the else text.
The issue is not letter case. What am I missing here?

I also ran a print test using this and it came back false, even though the test deal is definitely USD.

{% if deal.deal_currency_code == "USD" %}<p>usd text</p>{% else %}
<p>non-usd text {{ deal.deal_currency_code == "USD" }}</p>{% endif %}

Hey @Thompson_DHARMA

Check the type of the value using the type function:

{{ type(deal.deal_currency_codedeal.deal_currency_code) }}

If it’s not “str” try converting it using the string filter first.

Thanks Kevin! With your advice I did use the string filter but it’s still not working, unfortunately.
We’re tried all sorts:

{% if personalization_token('deal.deal_currency_code') == 'USD' %}
<p>usd text</p>
{% else %}
<p>non-usd text</p>
{% endif %}
{% set currency_code = personalization_token('deal.deal_currency_code') | string %}
{% if currency_code == 'USD' %}
<p>usd text</p>
{% else %}
<p>non-usd text</p>
{% endif %}
{% set currency_code = deal.deal_currency_code | string %}
{% if currency_code == "USD" %}
<p>usd text</p>
{% else %}
<p>non-usd text</p>
{% endif %}

I have solved this myself. I created a Module in Design Manager and entered this code.

{% set currency_code = deal.deal_currency_code | string %}
{% if currency_code == "USD" %}
<p>usd text</p>
{% else %}
<p>non-usd text</p>
{% endif %}
