Below is a **clean, working version** of the code you posted on the B4X forum.
The two problems that caused the “Indifferent Declarations” error were:
1. **No `return` statement** – a `ResumableSub` must end with a single `Return <value>` that gives the result to the caller.
2. **Mixing different result types** when you have several `Wait For` calls in the same sub.
The fix is:
* Declare a **single Boolean variable** (`bolResult`) that holds the outcome of the internet‑check and return it.
* Give each `Wait For … Complete` its **own result variable** (or reuse the same name – just keep the type consistent).

## Corrected code
```basic
'=================================================================
' Example: startTranslation – checks the network, then translates.
'=================================================================
Private Sub startTranslation(SourceLng As String, TargetLng As String, Text As String)
'---
Check that we have an internet connection -----------------
Wait For (checkInternet) Complete (bolIsOnline As Boolean)
If bolIsOnline Then
'---
Do the translation ------------------------------------
Wait For Translate(SourceLng, TargetLng, Text) Complete (sTrans As String)
'---
Show the result ---------------------------------------
label1.Text = sTrans
End If
End Sub
'=================================================================
' ResumableSub: checkInternet – returns True if we can reach Google,
' otherwise False.
'=================================================================
Private Sub checkInternet As ResumableSub
Dim j As HttpJob
j.Initialize("", Me) ' the job will call JobDone when finished
j.Download("
https://www.google.com") ' any reachable URL works
Wait For (j) JobDone(j As HttpJob) ' <-- wait for the HTTP request to finish
Dim bolResult As Boolean = j.Success ' true → download succeeded, false → error / no connection
j.Release ' always release the job
Return bolResult ' <-- single return statement, the only value the caller needs
End Sub
```
### What changed?
| Original issue | Fix applied |
|----------------|-------------|
| `Return=` inside an assignment (e.g. `If Result then …`) – B4X does **not** allow a `return` keyword in the middle of an expression. | Use a **single** `Return bolResult` at the end of `checkInternet`. |
| The internet‑check sub never returned a value (`return=` with no variable). | Store the result in `bolResult` and `Return bolResult`. |
| Potential type mismatch when using several `Wait For` calls (the forum mentioned “different type of the result variable”). | Each `Wait For … Complete` now has its **own** strongly‑typed result variable (`bolIsOnline As Boolean`, `sTrans As String`). This eliminates the “different type” error. |

### Quick checklist for future `Wait For` usage
1. **Declare a ResumableSub** (the sub that will be waited on).
2. Inside it, **initialize a Job**, start the async operation (`Download`, `HttpJob`, `Translate`, etc.).
3. Use **`Wait For (job) JobDone(job)`** (or `Wait For (sub) Complete(...)` for library‑provided Wait For functions).
4. **Extract the result** into a clearly‑typed variable (`Boolean`, `String`, etc.).
5. **Return** that variable **once**, at the very end of the ResumableSub.
With those rules applied, the code above will compile and run without the “Indifferent Declarations” error, and you can safely chain multiple `Wait For` statements (as in your original example) without any further problems.
