Pie Chart Given a Percentage

[cards18]

I'm trying to make a simple pie chart off a single percentage for a single data point.

AKA, I have a goal of $50,000
I have a given data point of $20,000
I have the progress percent calculated of 40%, but I want to see that as a pie chart.

I'm struggling and this seems ridiculously simple, but I can't get it to work.
Please help

Attaching the file for your use.......... click on the pie chart and it will show you how and where it is taking the data from.
