Google sheets checkmark conditional Formating

I need help with Google spreadsheet checkmark conditional formatting. Please see the image for a better understanding. When I click on the C2 cells checkmark then automatically A2 cells $10 will be selected and added to the E5 cells. When I click on the B6 checkmark then automatically A6 cells $40 will be selected and added to the E5 cells. Summary of the concept: When I checkmark any cells (from B2 to B9 & C2 to C9) the same row (From A column) number will be added automatically to the specific cells(to E5 cells). How do I do it?
