Greetings!

I have a cBizObjForm where I set the allowmulitpleinstances to FALSE to keep the user from shooting themselves in the foot. The framework catches the attempt to start subsequent instances, however, I receive this error when I click on the OK button of the message box:

Function argument value, type or count is invalid
Method: Scan
Object: MyApp.oforms

Here's the code that is happens on (the 'llFound =' line):
FOR lnRow = lnStart TO lnEnd STEP tnDirection
IF llCompareProperty
*---------------------------------------------------
*-- Look for either class name, object name, or both
*---------------------------------------------------
IF EMPTY(tcProperty) OR tcProperty = "CLASS"
----->>>>>>>>> llFound = UPPER(this.aChildren[lnRow, CHILD_CLASS]) == tuParm1
ENDIF

I've tried to trap the error and VFP 8 just throws up all over me and then throws me out to boot! VFP terminates!

Not sure what is causing this, but I just did a quick test for ALL the forms in this app that are set this way and I get the same error.

Any ideas?
