Deanne rasmussen asked 5 years ago
If (_MONTHLYIMPRESSIONSCALCULATED <> ” “) Then
Return _PRODUCTNAME & ” – “ & _MONTHLYIMPRESSIONSCALCULATED
Else
Return _PRODUCTNAME
End If
Here’s our formula – any suggestions? We get Error in ‘MsGpDestination’. Line ‘taSopLineIvcInsert___E55F45DF-CA20-4FA4-865B-A5D401054F6C’
Parameter ‘Item description’
Parameter set value event.
Return _PRODUCTNAME & ” – “ & _MONTHLYIMPRESSIONSCALCULATED
Else
Return _PRODUCTNAME
End If

The message “conversion from string ” ” to type ‘Double’ is not valid” is likely a result of comparing two values that are not related.
In your example, it is likely the calculated field “MONTHLYIMPRESSIONSCALCULATED” and the fact you are comparing it to a string value.
You can use the ToString function to convert the calculated field in both your If statement and the return statement, which should resolve your issue.
If (_MONTHLYIMPRESSIONSCALCULATED.ToString <> ” “) Then
Return _PRODUCTNAME & ” – “ & _MONTHLYIMPRESSIONSCALCULATED.ToString
Else
Return _PRODUCTNAME
End If

I am getting this same error and I am trying to do a calculated field for a dollar amount.
if _REN_FEESCHEDULE_REN_FEETYPE = “Deposit” then
return _REN_TOTALPRICE*.35
else
return _REN_TOTALPRICE
end if
I have tried ToString on multiple places, but get the same error.
Help and thank you.

Lorren Zemke replied 3 years ago Tanya, the reason ToString() doesn’t work for you is because your source column is already considered a string. You have to convert it to a number so you can do maths on it.
return Double.parse(_REN_TOTALPRICE) * .35
or
return Decimal.parse(_REN_TOTALPRICE) * .35
both statements will give you the same result.
