The new statement is placed at the bottom of the list of statements.

Note

You cannot paste statements from the If section of the Global Change dialog box into the Then or Else sections; however, you can cut or copy and paste between the Then and Else sections.

Combine text fields

You can use Global Change to modify text data items such as activity IDs and names, and activity codes by linking two text fields using the ampersand (&) operator. This is called concatenation. The following statement adds the Location activity code value to the Activity ID field, if a value is assigned to the activity:

Then: Activity ID = Activity ID & Location

Tip

Use a dash (-) or underscore (_) to represent spaces when concatenating data.

Use arithmetic with Global change

You can use mathematical equations to change numeric data such as quantities, costs, and durations. Use addition, subtraction, multiplication, and division to calculate new values. Click the Operator column to list the various operator symbols. Join text strings with an ampersand (&) symbol.

Developing Projects

Arithmetic operators can link two data items, a data item and a number, or two numbers that you enter. Use arithmetic operators in Then and Else statements to calculate new values for a data item. Arithmetic operations are not used in If: statements; only comparisons.
