It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

@Ruan17 , the issue you are trying resolve is not quite clear to me. Thus, I will try to cover all the scenarios I can think of. Below is the demonstration how to handle n8n variables inside the text.

Depending on where you stand the solutions are

Use expression making sure you turned it on

Evaluate text as an expression

Using $evaluateExpression() (see Convenience methods | n8n Docs).

Excellent, $evaluateExpression worked perfectly, I had never seen this function in n8n, and thank you for sending the support page, I will study it again, I thought I hadn’t updated it and taking advantage of it, do you have any links that help make better prompts within n8n?
