Using a migx tv to filter with msproducts

Hello,

I am currently developing an e-commerce multi site. I need to filter out products base on its territory. To filter out products, I have created a migx tv named product_prices which has a listbox tv that contain all of the territories where the product maybe available e.g country 1==c1||country 2 ==c2||country 3 ==c3, etc. Also I have 2 date tvs, Deal start date & Deal end date (with date and time options) within this migx, so I can filter out special deal products when a territory has a promotion. I've tried using the code below but nothing happens

[[!msProducts?
    &parents=`[[*id]]`
    &paginator=`pdoPageWrapper@naturesdiscount`
    &element=`msProducts`
    &class=`msProduct`
    &sortold=`ms|price:desc`
    &sort=`resource|menuindex:asc`
    &limit=`3`
    &tplOuter=`nd.tpl.mFilter2.outer`
    &tpl=`nd.tpl.msProducts.row`
    &tplFirst=`nd.Firsttpl.msProducts.row` 
    &tpl_n3=`nd.Thirdtpl.msProducts.row` 
    &tplLast=`nd.Lasttpl.msProducts.row`
    &includeThumbs=`246x246`
    &includeTVs=`store_deals`
    &where=`{"store_deals:find_in_set":"%[[!+storeCountry.code]]%","deal_end_date:>":"[[!current_time]]"}`
]]

My migx tv


Any suggestions as to how to solve this?
