I have a script that can process one of five fields. What I want to do is use a parameter to specify which field needs to be processed by passing a 1 to 5 and then storing the parameter to a local variable.

Then I want to use the Replace Field Contents script step to replace the field specified to a 1 or 0.

For example, I have the following fields:

Field1

Field2

Field3

Field4

Field5

The field number variable is $FieldNumber.

It looks like I have to select the field that I want to change instead of using the following:

Evaluate( "Field" & $FieldNumber )

Is there a way around this without using the "Set Field" in a loop.

The target field for Replace Field Contents[] cannot be specified dynamically. Using Set Field [] in a loop will not change the basic situation - only Set Field by Name[] will accept a variable as the target field.

The simplest solution, IMHO, is to place five Replace Field Contents[] steps in a If/ElseIf/ElseIf… block.

Alternatively, you could use Go to Object[] or looped Go to Field[] to select the target field, then perform Replace Field Contents[] without specifying the target field. However, this requires all five fields to be on the layout.

Note also that having five "similar" fields is usually a sign of inadequate data structure.
