How do you create a stored procedure with two parameters being a specific Id# and a datetime

Question

I am trying to create a stored procedure that retrieves a list of of vehicleID's and their corresponding most recent FixDate, if they have one. The problem I am having is finishing the last line, I was instructed to use something along the lines of 'vehList[x]'. When i try to use it it does not work and generate the list. Do I need to add another parameter and if so, how would I apply it.

I am getting an error message since I know it can't create the query but I don't know what to add to after 'where v.Code = ____'

The column I want to pull from is called 'VehicleID' when I try yo use it I get an error that says Ambiguous column name.

I am getting an error message.

Msg 8114, Level 16, State 5, Line 1 Error converting data type nvarcahr to bigint.

CREATE PROCEDURE LastFixTaken
@FixDate DateTime,
As SELECT Max(FixTaken) As LastFixTaken

From VehilceHistory vh
JOIN Vehicle v On v.VehicleID = vh.CehicleID
where v.Code = vehList[x]

I am not sure what to put after the v.Code as I am trying to retrieve a list of all Vehicles with a recent fix date if I insert a specific vehicle ID in strings the procedure works. I was told to use vehList[x] but that isn't working.

Any help would be greatly appreciated and if you have any further questions I'll do my best to help, thanks.
