### Answer Yes, you can implement a counter in Conversation Flow using dynamic variables and Code Nodes. [(1) ]() [(2) ]() Here's how to set it up: 1. Initialize a counter variable Set a default dynamic variable (e.g.,

attempt_count

) to 0 at the agent level or pass it when creating the call. [(1) ]() 2. Use a Code Node to increment the counter After each failed attempt, add a Code Node that increments your counter: [(2) ]()

javascript
// Increment the attempt counter
const currentCount = parseInt(dv.attempt_count || 0) ;
return { new_count: currentCount + 1 };

3. Store the incremented value In the Code Node settings, use "Store Fields as Variables" to save the result back to your dynamic variable (e.g., map

new_count

from the JSON path to

attempt_count

) . 4. Add transition conditions Create equation-based transition conditions to check if the counter has reached your limit: [(3) ]() -

{{attempt_count}} < 3

→ retry the question -

{{attempt_count}} >= 3

→ move to a fallback node This approach lets you control retry logic precisely while keeping track of how many attempts have been made. [(1) ]() [(2) ]() [(3) ]()

@AI Evy So i've got the loop. Extract variables, set variable (number) defaults to 0. It runs, new_count is 2. How can I debug this?

These logs will appear in the test output panel when using Run Code, and are also available in call logs. 3. Review Call History After making a test call, check the Call History to see how the conversation transitioned through each node. [(2) ]() This helps you verify if your transition conditions are working as expected. 4. Check your variable mapping Verify that in your Code Node's Store Fields as Variables section, you're correctly mapping the JSON path

new_count

to your dynamic variable

attempt_count

. [(1) ]() If the variable name doesn't match exactly, the counter won't update properly. 5. Verify transition conditions Make sure your transition conditions are checking the correct variable name and using the right comparison operators (e.g.,

{{attempt_count}} < 3

) . [(2) ]() If

new_count

is showing as 2 when it should be incrementing from 0, check that your initial default value is actually being set to 0 and that you're storing the result back to the same variable name you're reading from. [(1) ]() [(3) ]()
