How to display variable value in Head HTML code web part?

I have below code in head html code webpart

{% var image=""; if(condition){image="X";}else{image="Y";} %}

{% if(image != null) <meta content={% kenticofunction(image) %} > %}

Above meta tag is not displayed in html output. Not sure whether macros I wrote is in correct format or something fails

widget macro head webpart

I would recommend using the macro debug to see what are the resolved values and also check Event log for any errors.

you are doing macro inside macro, but incorectly.. kenticofunction must be a macro method. Try this:

{% var image=""; if(condition){image="X";}else{image="Y";} %}

{% if(image != null) ("<meta content="+ MacroMethod(image)+ ">")%}

Peter, That does not work. I see below error in event log

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

Anyhow I resolved using Custom Macro Method
