Below is my query:

Query: 
Private res As ResultSet = modSQL.mysql.ExecQuery("SELECT tblActivities.activityID, tblActivities.Activity, tblActivities.Status, tblCommodities.commodity, tblMOT.mot, tblLedger.amount FROM (((tblLedger INNER JOIN tblMOT ON tblLedger.motID = tblMOT.motID) INNER JOIN tblCommodities ON tblLedger.commodityID_fk = tblCommodities.commodityID) INNER JOIN (tblEngagements INNER JOIN tblActivities ON tblEngagements.activityID_fk = tblActivities.activityID) ON tblLedger.engagementID_fk = tblEngagements.engagementID) INNER JOIN tblEvents ON tblEngagements.eventID = "& evntID &"")

For additional information, I attached a screenshot of my database design:

Lastly, below is the error I'm having:

have you tested your select directly in your database?

note: when using inner join, if the record does not exist in any table, it will not display the record in your select.
an alternative is to use left join.

SQL: 
SELECT
   tblActivities.activityID
 , tblActivities.Activity
 , tblActivities.Status
 , tblCommodities.commodity
 , tblMOT.mot
 , tblLedger.amount
 
 FROM tblEngagements
 INNER JOIN tblEvents ON tblEvents.eventID = tblEngagements.eventID
 INNER JOIN tblActivities ON tblActivities.activityID = tblEngagements.activityID_fk
 INNER JOIN tblLedger ON tblLedger.engagementID_fk = tblEngagements.engagementID
 INNER JOIN tblMOT ON tblMOT.motID = tblLedger.motID
 INNER JOIN tblCommodities ON tblCommodities.commodityID = tblLedger.commodityID_fk
 
 WHERE tblEngagements.eventID = 1

This part definitely looks weird in your query:

B4X: 
... INNER JOIN tblEvents ON tblEngagements.eventID = 1

should be something like:
B4X: 
... INNER JOIN tblEvents ON tblEngagements.eventID WHERE tblEngagements.eventID = 1

EDIT: just noticed @Lucas Siqueira did use the correct WHERE construction. ;)

For what it is worth, sometimes when you have a charged up query with many references, it will look tidier if you use aliases. Here is an example:
B4X: 
Dim strQuery As String = $"Select
A.activityID
, A.Activity
, A.Status
, C.commodity
, M.mot
, L.amount
FROM tblEngagements En
INNER JOIN tblEvents Ev ON Ev.eventID = En.eventID
INNER JOIN tblActivities A ON A.activityID = En.activityID_fk
INNER JOIN tblLedger L ON L.engagementID_fk = En.engagementID
INNER JOIN tblMOT M ON M.motID = L.motID
INNER JOIN tblCommodities C ON C.commodityID = L.commodityID_fk
WHERE En.eventID = ?"$
Dim rs As ResultSet
rs=SQL.ExecQuery2(strQuery, Array As Object(evntID))
Also, keep in mind string literals and parameterized queries.

This really helps a whole lot. Thank you so much for this!
