When two or more reports with different prices are selected then the prices should be summed up. That total sum is the number to be displayed in the paragraphs located lower in the document.
That total sum is also the number to be used to subtract from the 200,000 and 100,00 figures in the paragraph.

for example if three reports are selected: green fleet report (€9,000), a efficient fleet report (€4,500) and a AQ report (€9,000) then the code should sum up the pricing set for each of these (€22,500) and display that figure in the paragraph.

I hope that answers your question, please let me know if im missing anything. Thank you
