### Parameter field considerations

There are a number of things to keep in mind when working with parameter fields:

- Parameter fields support the following data types:

  Boolean: Requires a yes/no or true/false answer.
  Example: Include planned budget numbers in the summary?

  Currency: Requires a dollar amount.
  Example: Display customers with sales over XXXXX.

  Date: Requires an answer in a date format.
  Example: Enter the start and end dates of the quarter.

  DateTime: Requires both date and time.
  Example: Display statistics for 07/04/1999 between 1:00pm-2:00pm.

  Number: Requires a numeric value.
  Example: Enter the customer identification number.

  String: Requires a text answer.
  Example: Enter the region.

  Time: Requires an answer using a time format
  Example: Display the total number of calls from 1:00pm-2:00pm.

- Parameter field prompting text can be up to four lines long with approximately 60-70 characters per line (depending on character width, up to the 254 character limit). Text over one line in length will automatically word wrap.
- You can create a pick list for the user to choose the parameter value rather than having them enter it manually.
- A parameter field does not have to be placed in a report in order to be used in a record or group selection formula. You create the parameter field and then enter it in your formula as you would any other field.
