Assistance required with Qlik Sense

Job ID: 35346601

Budget: €8 – €30 EUR

I have created a Qlik Sense project that is sales analysis with profit margin.
It works well but I have one problem. As per image attached profit can only be calculated per product if there is cost price associated. Some products do not have cost price associated (pink highlight), as a result I cannot get my sheet to show Total correctly (yellow highlight)
