Access Query

I have a macro running a series of queries. I keep getting the following error:
"This expression is typed incorrectly, or it is too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables."
I'm basically running reports for different projects. I select the project name from a combo, then I hit a command button (initiates a macro) to generate the results based on that project. It has worked for a number of projects, but when I select certain projects it doesn't work. There are no special characters in the project names either.
Not sure what would be causing this?

In the query (go to design), specify as Parameter:  


and select Date/time as data type.

If it works for some projects but not others, it is most likely a data issue.  You will need to run the steps of the macro one at a time to isolate the problem.  I'm not sure we will be able to resolve this without the actual database and since you shouldn't load private data to this site, we'll just hold your hand as you work through this.

Above is the message, I assume its the query? (tables are sql tables). If I remove this column from the query, it seems to run? Yet it worked on others!!!

Start Date
Between [tblProjectTeam]![StartDate] And Now()

Think this is what is causing it...

Hi Pat

Thanks for this, I will check the data in the underlying tables tomorrow and let you know how I get on. If that doesn't work, ill run the queries one by one.
