exercise2.2 Pass “contain all columns for 2nd Jan 2020” “”
exercise2.3 Pass “not allowed to use select keyword” “”
exercise2.3 Pass “return correct values for temp” “”
exercise2.3 Pass “return correct values for wind” “”
exercise2.3 Pass “return correct values for all” “”
exercise2.4 Fail “when given the wrong option return error \”<mysensor> is not a valid option for mysensor – valid options include `temp`tyre`wind`all\”” “”
exercise2.5 Pass “func should return same result as before” “”
exercise2.5 Pass “`p attribute exists” “” </p><p><br></p><p>I couldnt find where is error causing, as i saw the result of error message is returning as expected. Please see the screenshot below for the .f1.checkSensor</p><p><br></p><p>my code for error trapping <br>if[0b=mysensor in key this_dict; .Q.trp[‘string[mySensor],” is not a valid option for mysensor – valid options include `temp`tyre`wind`all”]]; </p><p><br></p><p>To run:</p><p>.f1.checkSensor[raceDay;lapTable;`temperature] // should errorResult return:
“temperature is not a valid option for mysensor – valid options include `temp`tyre`wind`all”

Can you paste your code for this question here please? Looks good at a glance so could be something small that needs tweaking
