Discount Amount not display / Fetching in invoice column

dear experts I want little help, see this image, discount amount total not coming in column total, I added this but not getting total of this column, see this image and code

Local: Field: KA Discount Amt: Set as:$$CollAmtTotal:InventoryEntries:$Discount

 

@Amit Kamdar sir I added this

Local: Field: KA Discount Amt:Set as:$$Total: KA Discount Amt

i also added this - Local: Field: KA Discount Amt:Set as:$$CollAmtTotal:InventoryEntries:$$Total:KA Discount Amt

but after loading this tally quit and showing Bad Formula

 

if it is an attribute of the InventoryEntries(Collection) then use like this:

Code:

$$CollAmtTotal:InventoryEntries:$KADiscountAmt

else

you have to add this one to the part where InventoryEntries are repeated
Total :KADiscountAmt

and in the field where you want to set
setas :$$Total:KADiscountAmt

 

@teja varma Bhai and @Amit Kamdar sir I have added customized discount tdl in tally, in tally default discount is % basis but I want amount wise so I added a tdl, I think the problem comes from this tdl , see this tdl , cash discount
