I'm trying to do some math on currency values (divide one by another to get a percentage discount) in 7.5.4 web.  the error I am getting is "cannot convert from 'decimal?' to 'decimal'"  I have a feeling that this has something to do with how SLX stores/creates currency fields but can't figure out how to work around it.

decimal? is a nullable variable

If you have a variable of type decimal? you need to do this:

// decimal? theDecimalQValue  -- This is the variable we are reading from

decimal myValue = theDecimalQValue.HasValue ? theDecimalQValue.Value : 0;

Never mind guys.  I was able to convert the currency value to a decimal using System.Convert.ToDecimal(currency).

Interesting fix, but it worked.

Just keep in mind that decimal? is a nullable object.

So, if you have this code:

decimal? SalesPotential = null;

if you then do:

decimal sp = System.Convert.ToDecimal(SalesPotential); 

you will probably end up with an exception

Better off testing your object:

if (SalesPotential.HasValue)

{

//do something

        decimal sp = SalesPotential.Value;   (The Value property of SalesPotential is actually defined as decimal

}

Here is some reference material for Nullable Object Types:
