FPW has a limit of 5 nested READ. Let say that you have 6 screens (A to F). On each form, you have a command button that call another form (screen A call screen B, screen B call screen C, etc.) On each form, you have a series of @...GET and a READ.

Screen A is shown (First level READ)
Screen A call screen B (Second level READ)
Screen B call screen C (Third level READ)
Screen C call screen D (Fourth level READ)
Screen D call screen E (Fifth level READ)
Screen E call screen F (Error, 5 levels of READ max.)

You have to play gymnatics to get around this limitation (with a READ foundation, clearing inactive screen READ, checking the value of ReadLevel(), etc.)

>I am having a problem where I am getting a message "Too many READs in effect."... can anyone provide any insight or offer some suggestions about this error... I have read what FoxPro has on the READ command, but I am still not clear about this problem of "NESTED READS"... any help provided would be greatly appreciated!
