Hi,

i guess you want to use the attribute function. to access the value of attribute_%{iteration} you usually do

attribute("attribute_"+%{iteration})

There are some more things you can do with the # notation instead of %, but i always forget them and need to ask @David_A

Best,

Hi,

the attribute() function is exactly the thing you're looking for. It will resolve the macro value first and and then looks the combined string as an attribute name. With the # you could basically do the same, but the function is the more readable approach.
