Instead of:
NAME = #Evaluate("tempvar")#<br>
Remove the quotes:
NAME = #Evaluate(tempvar)#<br>
The first line is evaluating the string expression "tempvar" which returns
the field names. By removing the quotes you are telling the Evaluate
function to evaluate the contents of the variable Tempvar, i.e. evaluate the
fieldnames which results in the values.
