How can we add a clip to add an attachment in this code?

{% assign cost_groups = custom.financieringeenmans %}
_**FINANCIERING**_
{% if custom.detail.goederen == blank %}{% assign goederen_range = '65'%}{% else %}{% assign goederen_range = custom.detail.goederen %}{% endif %}
{% assign goederen = period.accounts | range:goederen_range %}
|---------------------|-------10%-------:+ {% fori financieringeenmans in custom.financieringeenmans %}
|{% input financieringeenmans.naam %}|{% endfori %}
             
            
              
              
              
            
            
           
          
            
              
                sven
                
              
              
                  
                  
              2
              
             
            
              That’s a new variable you’ll have to create, and the way to do it is use this filter : as:annex
for instance: {% input financieringeenmans.bijlage as:annex %}
             
            
              
              
              
            
            
           
          
            
            
              This gives me this result:
What am I doing wrong?

              Hello @Fiduciaire.Eulaers,
I see we forgot to answer this; so sorry 'bout that.
The answer is this however :
{% input financieringeenmans.bijlage as:file %} 
My mistake. And apologies again for the delay
