# Verb sub task
A sub workflow is an element in a User step
 \
**There are three types of sub workflows:**\
**Check List:** Executes one workflow for each record in a list of things to do.\
**Item Creation:** Creates a new item for each time the sub workflow is executed.\
**Verb:** A side track in the workflow where the sub workflow can be executed one or many times.
### Verb Sub Task
A sub workflow is created from a *User Step*. Create a new *User Step* and add a verb sub-task element. Configure the appearance of verb sub-task element in the client.
Set the following:
* **Title:** Text on the verb sub-task element button.
* **Icon:** Icon one the on the verb sub-task element button.
* **Allow Multiple Runs:** This should be check to allow the verb sub-task element to be run multiple times whist in the same user step in the main workflow.
* **Pills:** Pill on the sub workflow button. One or multiple pills can be configured on the verb subtask, the pill can display a text or a count of how many times the verb sub-task has been run\*
Close the *User Step*, an icon will now appear, representing the added sub workflow.
Double click on the sub workflow icon to open the (empty) sub workflow.
Create a workflow, all variables from the main workflow are available in the sub workflow.
Return data back to the main workflow by configuring the *End step* in the sub workflow. The output from the sub workflow is put in the target variable of the verb sub-task element. The sub workflow output is available once the user has moved on from the user step the verb sub-task is located in, i.e. it is not possible to use the data in the user step the sub workflow is started from.
The output from a sub workflow will always be in grid format.

5\. Script Step: outPutPictures

7\. Assignment: selectedMaterial
8\. User Step
Sub verb-tasks run in iOS - Pills:
#### Flow script examples
Scrip Step - Add pictures to table:
```
let table1 = table(data, filename);
for rec_ in value3 do
set table1 = table1 & [data: rec_.addPicture.data, filename: rec_.addPicture.filename];
done
return table1;
```
Scrip Step - Grid ? verb sub task run multiple times (loop in loop):
```
let table1 = table(part_no, part_desc);
for rec_ in value4 do
for rec1_ in rec_.gridMaterial do
set table1 = table1 & [part_no: rec1_.part_no, part_desc: rec1_.part_desc];
done
done
return table1;
```
Assignment ? fetch first picture:
```
Picture = {(*First(value3).addPicture)}
```
Assignment ? fetch last grid:
```
selectedMaterial = {value4.Skip(value4.Count()-1).First().gridMaterial}
```
