Yes/No Parameter Query Upload Images   Link   Email  
Alan Welch 
I have a table with a bunch of fields that are yes/no. If I enter true in the appropriate criteria box, it works fine. If, following the instructions in Beginner 5, I set it up for paramater input, and enter true in the parameter box, I get an error message "the expression is typed incorrectly of is too complex to be evaluated". I viewed the lessons on forms but did not find any help there. Any suggestions? TIA Al Welch

Good question. "True" in a parameter box returns a string. Your yes/no fields are technically numeric. So, you'd need to enter 0 or -1 for your parameter prompt. Yes, -1 is the value for True. Confusing... I know. Someone else recently asked me about this. I was going to do a video on it soon.

Or set the parameter in the Parameter Window.
