Question : Summing values based concatenated date and variable

Dear experts,

Need a formulae which concatenate values in cell A6 and D1 in one set and A6 and D2 as another set.
and then using these two date intervals concatenated by variable in cell A
sum values in sheet xyz column B by vlookup range values in column D
The dates can be in random order in sheet xyz column


I should be getting zero value for the variable but iam getting a value.

I think the formulae will require some fix

thank you
