I have a loop
While numberVariable > 0 {
variable.temp = fixedString+numberVariable (append)
Now I want to do %fixedStringnumberVariable% to get its value
END-REP
%%variable.temp%% doesn't work.
Put another way, variable 1 = variable 2's name.
If I have variable 1, how do I get the value of variable 2?
This form of "indirect reference" doesn't exist within Rule Machine; the closest you can get would be the Token method for extracting delimited values from a String variable with a variable index, e.g.:
Just spitballing here, but if you built such a structured list (using a loop early in your rule), then it would be easy to pull indexed values as needed into a dummy/placeholder variable (I called mine 'extract' here), which then gets used later in your URL builder string (e.g. %extract%). No more need for indirect!
