I' using the following code:
DoCmd.OpenForm "frm_Legend", , , "[Symbol] Like " * "'" & Me.Scenario_Code & "'"

however I get an error message Run Time Error 13 Data Mismatch -- any thoughts on how to correct.

Is Symbol a text field?  If it isn't, you can't use Like at all since Like implies a text field and you will get incorrect results if you are comparing to a numeric value or date.
Are you really passing a partial string?
Like is very inefficient so you never want to use it unless you actually need it.

If you are using Like because you want the symbol to be optional, then do the following instead:

If Me.Scenario_Code & "" = "" Then
    DoCmd.OpenForm "frm_Legend"
else
    DoCmd.OpenForm "frm_Legend", , , "[Symbol] Like " * "'" & Me.Scenario_Code & "'"
End If

Open in new window

Still get error 13.
I trying to drill down to another form and display the matching value.


Scenario_Code Field                       Symbol Field
CO01.03                                             CO

Compare the first 2 char of the scenario_code field with the Symbol field

The code did not error but it did not find the Symbol code

Scenario_Code Field                       Symbol Field
CO01.03                                             CO

if this is your example, you need to place the * by the end

DoCmd.OpenForm "frm_Legend", , , "[Symbol] Like '" & Me.Scenario_Code & "*'"

to make sure,
In your form you have the text CO01.03 and you are placing by the criteria CO
DoCmd.OpenForm "frm_Legend", , , "[Symbol] Like 'CO*'"

How about if we take the left 2 char of the Scenario_Code  field and compare to the 2 digit Symbol field or vice versa??

so you will need to use the left function
DoCmd.OpenForm "frm_Legend", , , "[Symbol] ='" & Left(Me.Scenario_Code,2) & "'"
