Hello Experts,

I am working on a transaction/traffic conversion rate. I've written VBA funtions which gather the traffic count and transaction count. Each function works fine individually, but when I try to divide one by the other, I recieve an Run-time error'13': type mismatch .

Here are the main pieces of code:

    Dim TrafficCount As Variant

    TrafficCount = TrafficOut(BegDate, EndDate)
    Range(Cell).Value = TransactionCount(BegDate, EndDate) / TrafficCount    
    ...

Function TrafficOut(BegDate1, EndDate1) As Variant
...

Function TransactionCount(BegDate1, EndDate1) As Variant
....

Thanks

Hi,

Why are you using Variant data types for TrafficCount, & the two functions?

If you define these as Long (or Double) data types, does this result in a different error (or do you see the required outcome)?

BFN,

Something else is going on because this works.
Sub test()

Range("A1").Value = TrafficOut(2) / TransactionCount(2)

End Sub
Function TrafficOut(x) As Variant
TrafficOut = x * 25
End Function
Function TransactionCount(x) As Variant
TransactionCount = x * 5
End Function

Open in new window

Let me also add to what fanpages said. Variants should only be used when absolutely necessary because they are larger and slower than any other variant type, so not only should your functions return appropriate data types but the parameters passed to the functions should also be given .

What does it mean to be "Always On"?

BFN, your question prompted me to revisit the previous solution. I just needed to add (0,0) to my function call return.

    TrafficOut = rs.GetRows(-1, 1, "TrafficOuts")(0, 0)


Thanks:)

MartinLiss and Fanpages, thanks for your suggestions. I'll have to revisit the Variants usage some other day.
