hi all, i'm providing details of problem i'm facing. I have to extract values from a server response, save in a variable and pass along with URL of next HTTP request. Lets say reqA generates resA. in reqB there is variable hotelNumber=1 append in URL. Now i'm using Post-Processer Regular Expression Extractor to extract value from resA with Reference Name:HN/Regular Expression:hotelNumber=(.+?)/Template:$1$/Match No:1. now in HTTP Request sampler, i'm using Pre-processer user parameters with name:hotelName/user_1:$HN(as reference name in Regular Expression Extractor ). but value of hotelNumber not appending with reqB. where am going wrong?
