Change the relevant data type for the columns in the dataset itself and use it in the crystal report then the data type will be identified by the crystal report and you can do the total ,etc.

Let try this:

Assumpt that you have
Quantity Column- Character type

1. Create new column based on data Quantity column and convert data to number call QuantityNum
2. Use QuantityNum to display in report
3. calculate this field as you want to do.

It is worked.

Within Crystal, we have two type of syntax.

So you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

C#

If NumericText ({field}) then ToNumber ({field}) else 0

you also use the Val() function to do that. you can see more details (Val vs ToNumber here http://kenhamady.com/cru/archives/81[^] )

and the others convert type here http://crystaltricks.com/wordpress/?p=149[^]

hope that is useful for you
