I have a form that has only a pageframe wiht 2 tabs. It's tree structure looks like this.
frmSuptit1
pgfbizSuptit1
pag1
control1a
...
chkSuptitLaction a logical field with a checkbox
...
control1z
pag2
control2a
...
txtSuptitcbte1 a text box
...
control2z


In the txtSuptitcbte1.lostfocus method (on pag2) I want to establish the value of chkSuptitLaction.value (which is on pag1) with a
IIF(This.value = space(12), .T. , .F. )

but I have a very hard time with This, Thisform, Thisset, This.parent and I have just about tried every combination to no avail.

What should be the This?????.chkSuptitLaction.value =

based on the above hierarchy.

I keep getting "Unknown member chkSuptitLaction"

Thanks
