Sharepoint List Conditional column formatting based on date range

[MonsoonDesign]

Hi you clever people,

I am trying to get a DUE DATE column in my list to show red when the BID STATUS is 'Go', and the DUE DATE is within 5 days from now. To test it, we coded it so that it would colour any future dates. However, it's not colouring anything. Here is the code we have:

{
"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
"elmType": "div",
"attributes": {
"class": "=if(((Number([$Submission_x0020_due_x0020_date]) - Number(@now)) > 0) && [$Bid_x0020_status] == 'Go','sp-css-backgroundColor-blockingBackground50', '')"
},
"children": [
{
"elmType": "span",
"style": {
"display": "inline-block",
"padding": "0 4px"
}
},
{
"elmType": "span",
"txtContent": "@currentField"
}
]
}

  Can anyone advise what we are doing wrong? And why none of the dates are showing red?

Try using below JSON code, it should work for you:

{
    "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
    "elmType": "div",
    "attributes": {
        "class": "=if(([$Submission_x0020_due_x0020_date] >= @now && [$Submission_x0020_due_x0020_date] <= @now + 432000000) && [$Bid_x0020_status] == 'Go', 'sp-css-backgroundColor-blockingBackground50', '')"
    },
    "children": [
        {
            "elmType": "span",
            "style": {
                "display": "inline-block",
                "padding": "0 4px"
            }
        },
        {
            "elmType": "span",
            "txtContent": "@currentField"
        }
    ]
}

Make sure you are using correct internal name of Submission due date and Bid status columns.
