Help with line chart with multiple lines

[JGH1]

Hello,

I must be missing something obvious because I've read several posts about this issue and still cannot add multiple lines to my line chart. Some of the posts I've seen shown a version of Power BI that not has different options for line charts. I'm trying to set my "sets" to the x-axis, the "concrete test result" to my y-axis, and have multiple lines for the "test times", ie 5 hrs, 10 hrs etc. However, shown below is what I have. I've tried multiple manipulations without success. Can someone please help me?

It's got 'COUNT of test result' selected as the plot value.  I don't know how your data should be modelled or how values/sets relate to each other but I don't think you want to count the test results.

Thanks @HotChilli. Would you mind helping me with how I do this? The data is already a decimal number. I don't know how to stop it from "Counting".
