Feedin payments giving the wrong figures

as the PV output is in cents and the uk is in pounds i can not get the figures to come out right we now get £0.5275 feedin payments .
on the 14-5-18 I got 26.384KW that should be £13.91 but it is coming out at just £0.94 in tariffs what do i have to put in each box to make it correct. Thank you

The FIT rate entered for the system is 3.57 and the generated amount on 14 May was 26.384kWh

The result is 26.386 * 0.0357 = £0.94

Hi I can see now i had the feed-in tariff in the wrong box I have been advised to use the figure of 54.61 as that is [ 52.75p] the Feed-in rate plus half of the Export tariff [3.72/2= 1.86p] that works great giving the total return on the generated electric.
