Attaching an expression to a parameter
You can create an expression in the Parameter form to:
- Implement mathematical calculations
- Use the expression when both equation and expression are specified
- Retrieve, compare, and calculate values in the database for a formula. For more information, refer to Parameter- field descriptions. For more information refer to Parameter- field descriptions
To perform a calculation using expression:
- The expression must be specified using the existing parameter.
Example:
In the expression ALCOHOL= [ALANINE] +10.
ALCOHOL is the parent parameter.
ALANINE is the dependent parameter.
- These parameters must be specified in the lab.Note:
- You can perform the calculation for a formula using Perform Calculation option.
- The dependent parameter must be specified after the parent parameter on the Parameters tab in the Lab form.
