To achieve the functionality where you submit a DataCard value based on either a dropdown selection or a TextInput in PowerApps, especially when you have a condition that shows a TextInput if the dropdown selection is "Other", you can use an If statement within the DataCard's Update property. However, the correct syntax and logic are crucial to avoid errors.

Here's a step-by-step guide on how to set this up:

Step 1: Setup Your Dropdown and TextInput

Assume your dropdown control is named Dropdown1.
Your TextInput control is named TextInput1.
The dropdown has a choice called "Other", which, when selected, makes TextInput1 visible.

Step 2: Configure the Visibility of TextInput1

Set the Visible property of TextInput1 to:

Dropdown1.Selected.Value = "Other"

This makes TextInput1 visible only when "Other" is selected in Dropdown1.

Step 3: Configure the Update Property of the DataCard

To submit the value from either the dropdown or the TextInput based on the condition, you will use an If statement in the Update property of the DataCard. The Update property should be set to something like this:

If(Dropdown1.Selected.Value = "Other", TextInput1.Text, Dropdown1.Selected.Value)

This If statement checks if the selected value of Dropdown1 is "Other". If it is, it uses the text from TextInput1 for the update. Otherwise, it uses the selected value from Dropdown1.

Common Mistakes and Solutions

Incorrect Control Names: Ensure the control names used in the formula match exactly with those in your app.
Data Types Mismatch: Make sure the data types expected by the DataCard's Update property match with what you're providing. For example, if the DataCard expects text, both parts of the If statement should return text.
Complex Data Types: If your dropdown is bound to a complex data type (e.g., a table), you might need to adjust the formula to reference the correct property, like Dropdown1.Selected.Text instead of Dropdown1.Selected.Value.

By following these steps and considerations, you should be able to configure your DataCard to submit data based on either a dropdown selection or a TextInput value without encountering errors.
