Concatenate Columns

Hi Everyone!!

I am attempting to concatenate values of a column and am having problems:

Dimension Variable:

Chart Data = "'[" + [Milestone Name] + "',new Date(" + [Creation Date Year] + ", " + [Creation Date Month] + ", " + [Creation Day] + "), new Date (" + [End Date Year] + ", " + [End Date Month] + [End Day] + ")]"

All Dates are Dimenstion Variables to separate out the required format.

Dimension Variable:

Conc Chart Data = Previous(Self) ForEach([Milestone Name]) + "," + [Chart Data] ForEach([Milestone Name])

I have also tried:

Conc Chart Date = Previous(Self) + "," + [Chart Data]     (same results as below except last Conc Chart Data is blank)

I am attempting to concatenate the data in ascending order for use in a javascript chart, but have not been successful in getting the information together.

Any Ideas???

Thanks,

Wendy
