I have an MS Access form with a project_ID field combo box and several other fields. Once the user selects the project_ID field, majority of the subsequent fields on the form are automatically populated. I am trying to add a field on the form that displays information not only based on the project_ID but also a Trans_ID. The catch is that I want the Trans_ID to be a text box on the form, in which the user can simply type in the Trans_ID and in another text box, the Error_DTL_1 field is displayed. This is the VBA code that I have generated so far:
Private Sub cboProjectID_Change()
Dim VarComboKey As Integer
Dim VarObjective As Variant
Dim VarStartDate As Variant
Dim VarEndDate As Variant
Dim VarRiskCategory As Variant
Dim VarTarDatSet As Variant
Dim VarErrorCount As Variant
Dim VarErrorCode As Variant
Dim VarErrorDTL As Variant
VarComboKey = Me.cboProjectID.Value
VarObjective = DLookup("[Objective]", "[Project_HDR_T]", "[Project_ID]= " & VarComboKey)
Me.txtObjective = VarObjective
VarStartDate = DLookup("[Start_Date]", "[Project_HDR_T]", "[Project_ID] = " & VarComboKey)
Me.txtStartDate = VarStartDate
VarEndDate = DLookup("[End_Date]", "[Project_HDR_T]", "[Project_ID] = " & VarComboKey)
Me.txtEndDate = VarEndDate
VarRiskCategory = DLookup("[Risk_Category]", "[Project_HDR_T]", "[Project_ID] = " & VarComboKey)
Me.txtRiskCategory = VarRiskCategory
VartxtTarDatSet = DLookup("[Targeted_Dataset]", "[Project_Targeted_Dataset]", "[Project_ID] = " & VarComboKey)
Me.txtTarDatSet = VartxtTarDatSet
VarErrorCount = DLookup("[Count_Error_Codes]", "[Project_Error_Final]", "[project_ID] = " & VarComboKey)
Me.txtErrorCount = VarErrorCount
VarErrorCode = DLookup("[ErrorCode]", "[Project_Error_Final]", "[project_ID] = " & VarComboKey)
Me.txtErrorCode = VarErrorCode
VarErrorDTL = DLookup("[Error_DTL_1]", "[Project_DTA_REV_T]", "[project_ID] = " & VarComboKey And "[Trans_ID] = forms![Quality Risk Assessment]!me.stTransID")
Me.txtErrorDTL = VarErrorDTL
End Sub
The two lines before the "End Sub" are my attempt at attacking this code. But every time i make a selection in the Project_ID combo box on the form, i get an error "Run time Error 13, Type Mismatch".
Can anyone help?
In the line...
VarErrorDTL = DLookup("[Error_DTL_1]", "[Project_DTA_REV_T]", "[project_ID] = " & VarComboKey And "[Trans_ID] = forms![Quality Risk Assessment]!me.stTransID")
...the "And" is outside the quotes, and the second clause seems to mix both the Forms! and me. ways of referencing. Try...
VarErrorDTL = DLookup("[Error_DTL_1]", "[Project_DTA_REV_T]", "[project_ID] = " & VarComboKey & " And [Trans_ID] = forms![Quality Risk Assessment]!stTransID.Value")
...and see if it works better. Alternatively, you could try...
VarErrorDTL = DLookup("[Error_DTL_1]", "[Project_DTA_REV_T]", "[project_ID] = " & VarComboKey & " And [Trans_ID] = " & me.stTransID.Value)
