What could be the problem with this INSERT with ADO parameters?

Trying to debug a procedure that writes data to an Interbase database.
I am using an Intersolve ODBC driver and ADO in Excel VBA.
This is done in a loop and I used to do this without parametrized queries and I am now doing this
with parameters, but sofar no success yet.

This is the simplified code where arr is a variant array made by assigning an Excel *** range to that array.
EntryIDArray and EncounterEntryIDArray are 1-D Long arrays.

2100 strSQL8 = "INSERT INTO " & _
"ENTRY(ENTRY_ID, ADDED_BY, UPDATED_BY, " & _
"READ_CODE, TERM_ID, ENCOUNTER_ID, " & _
"SECURE_TYPE, ADDED_DATE, UPDATED_DATE, " & _
"FREE_TEXT, DORMANT_FLAG, ENTRY_TYPE, " & _
"START_DATE, END_DATE, PROBLEM_ID, " & _
"ENTRY_FLAGS, PATIENT_ID, " & _
"SUBJECT_TYPE, TERM_TEXT) " & _
"VALUES(?, ?, " & lLoggedInUser & ", " & _
"?, ?, ?, 1, " & lCurrentDate & ", " & lCurrentDate & ", " & _
"?, 0, 13, " & _
lCurrentDate & ", 0, ?, '', ?, 'M', ?)"

2120 Set cmdADO8 = New ADODB.Command

2130 With cmdADO8
2140 Set .ActiveConnection = ADOConn
2150 .CommandType = adCmdText
2160 .CommandText = strSQL8
2170 End With

'this runs in the loop
3150 cmdADO8.Execute adExecuteNoRecords, Array(EntryIDArray(i), arr(i, 17), _
arr(i, 6), arr(i, 14), EncounterEntryIDArray(i), _
arr(i, 8), _
arr(i, 16), arr(i, 1), arr(i, 7))

It falls over after running fine for a few loops on the above statement.
It actually crashes Excel, so I have added a log to a text file and when it falls over the
parameters seems fine:
6876398,16,"ja2S.","AHVLX",6876396,"FOR EXTERNAL USE ONLY",5669941,1406,"CAPSAICIN 0.025% cream 45G"

There is an error handler, but as Excel just crashes on the above statement that doesn't help me.
I suppose there has to be something wrong with:
Array(EntryIDArray(i), arr(i, 17), _
arr(i, 6), arr(i, 14), EncounterEntryIDArray(i), _
arr(i, 8), _
arr(i, 16), arr(i, 1), arr(i, 7))

But I can't see it yet, particularly as it runs fine with parameters that seem similar as the one above.
The variables in the query, lLoggedInUser and lCurrentDate are fine.

Thanks for any advice.
