Multiple IF(ISNUMBER(SEARCH...), need sum

Hi - this is my first post into this forum & I'm hoping you all can help.

I'm trying to consolidate a formula with a lot of =IF(ISNUMBER(SEARCH...) components. It's probably best if I show my example.

If I'm creating a product bundle where each piece has a different price, I want the formula to add the prices depending on which products I choose to include in the bundle.

Column A is the product number.
Column B is the price.

For the example, cell B9, is the bundle I'm creating with 2 or more of the products.

Right now I can get the answer I need with =IF(ISNUMBER(SEARCH($A$2, B9)), $B$2,0)+IF(ISNUMBER(SEARCH($A$3, B9)), $B$3,0)+IF(ISNUMBER(SEARCH($A$4, B9)), $B$4,0)+IF(ISNUMBER(SEARCH($A$5, B9)), $B$5,0)+IF(ISNUMBER(SEARCH($A$6, B9)), $B$6,0), but this will be super time consuming to make if I have 20 products in a potential bundle.

Please see attached for specific spreadsheet.

Thank you!
