Passing Value At Run Time

Typically the way to to parameterize a dataflow is to utilize a separate webform dataset with your value you want to filter on. You'll also include a second column in your parameter dataset called "Join Column" and set it to a constant value like 1. You then can utilize the dataflow to add the same constant to the data set you want to filter / parameterize and then join the two datasets together. You can then do filtering based on the dataset and the parameter / webform dataset value.
You can then update the webform dataset to update the parameter you want to use within the dataflow.
