Again I don't have VFP available here (I'm in KC at the moment) and I haven't used it in a while, but..)

First off, make sure you check to see if the grid exists before trying to remove it - something like 

If vartype(ThisForm.grdFindQuote)<>'U' (I think that's right..)

Then to instantiate the grid use ThisForm.addObject("grdFindQuote") ..

I'm getting rusty - there is Addobject and NewObject - one lets you specify the classlib and one uses the currently selected classlib IIRC.

Once you instantiate it, you'll need to set Top and Left values to position it and set recordsource if it wasn't already specified in the class.
