Linking objects to a data source
To create a new lookup table:
1.
Select the F ILE >N EW menu command. This displays the C REATE N EW dialog box.
2. Select the O THER tab and L OOKUP T ABLE . This opens a new lookup table.
3. In the K EY column enter the string expressions to be flagged for substitution.
4. In the V ALUE column enter the substitution value. This can be:
• another text string (text or numbers)
• an asset (when dragged into the Value column it appears in bold to indicate
that it’s an asset)
5. To delete the contents of a row, click in the gray cell to the left of the row (this selects
the entire row) and press the DELETE key.
6. To save the lookup table, press CTRL + S.
Now that the lookup table exists it must be applied to a specific data source. Refer to
“Applying lookup tables” below.
Applying lookup tables
A lookup table will not work until you apply it to specific data or text.
How you apply a lookup table depends on where the data is coming from:
•
If data is being fed in from a data source, you would use the L OOKUP T ABLE row in the
P ROPERTIES B ROWSER .
• If the lookup table is replacing text coming from somewhere other than a data source,
e.g. the contents of a text box being set into another text box, you would use the
E
XPRESSION B UILDER to create a LOOKUP expression. Since this requires using the
Action Editor, you may want to read the chapter “Adding logic to control objects” on
page 10-1 (which also includes a section on the Expression Builder) before proceeding
to the instructions on how to create a LOOKUP expression.
To apply a lookup table to data from a data source:
1.
Open the asset to which the lookup table will be applied (e.g. control panel or template).
2. Select the control object to which you would like the lookup table applied.
