Javascript eval function equivalent in Crystal Report 10

[bether]

Does CR10 have an equivalent for the javascript eval function. This takes a string argument and return its value.

I'm building a report where the user specifies the fields they want to be included in the report. The columns/fields are not known at design-time. At runtime, I take the column name in a string variable, and will have to get the column value. How can I get the column/field value, given only the name?

Thanks!

You should qualify this a bit more.

Do you mean that the user will use parameters to determine which fields are returned?

Crystal isn't brilliant with ad hoc reporting from a users standpoint, but you can code it as in:

if {?MyParameterChoice} = "City" then
{table.city}
else
if {?MyParameterChoice} = "State" then
{table.state}
else
if {?MyParameterChoice} = "Zip" then
{table.zip}

Crystal doesn't allow for pass through of a value and then display the value of the column of the same name. In fact, you need to return the same data type or convert it within a formula to the same type.

Thanks!! Yes, I failed to mention that user will use parameters to determine the fields.

This works. Just thought there's an "eval" like function.
