Hi Jane,
there are multiple errors you have to address. Firstly, your rvi file is not defined correctly. Here is the link which tells you how to define a rvi file and how to use ReadVarsESO. First couple of lines have to be eplusout instead of 9th_parame... as in your example. File has to end with 0 and between you specify outputs you would like to extract from eso file. These outputs have to be defined in idf/imf file. Output:variable and Output:meter objects are places where you specify desired outputs. "Infiltration rate" is not among available outputs. However you can have "Zone Infiltration Air Change Rate" (or "Zone Infiltration Standard Density Volume Flow Rate") as an output. Similarly, "setpoint temperature" is not on the list of available outputs. You can use "Zone Thermostat Air Temperature" instead. Available outputs can be found in rdd and mdd files (after simulation is executed for a first time). Your rvi file should be:
eplusout.eso
eplusout.csv
Zone Infiltration Air Change Rate
Zone Thermostat Air Temperature
0
Secondly, jEPlus parameter definition in your case require "double" value type instead of "discrete". You can see in the preview box that you have an error.
Thirdly, search tag (@@...@@) you define in parameter definition has to be inserted in the idf/imf (model) file at the correct location. In the case of an infiltration rate it should replace 0.014 !Design flow rate (based on your screenshot). You also need to define second parameter (setpoint temperature), assign search tag and insert search tag in the model at appropriate location (it will be in setpoint schedules). You can find a lot more in the jEPlus manual on the following link
