I'll try it, never hurts. Now I'll let you know when it works,
Thanks already

If you believe it's the FldInsert function, perhaps you should try to
use
FieldPtr SetFieldTextFromStr(Word fldID, CharPtr str) functions posted
on
this newsgroup in the past. I don't know if this helps your and your
cause,
but it's worth a shot.
/***********************************************************************
*
* FUNCTION: SetFieldTextFromHandle()
*
* DESCRIPTION: Sets Field Text by using a Handle
*
* PARAMETERS: - fldID
* - txtH
*
* RETURNED: field pointer
*
***********************************************************************/
FieldPtr SetFieldTextFromHandle(Word fldID, Handle txtH)
{
Handle oldTxtH;
FormPtr frm;
FieldPtr fld;
// Get the Active Form
frm = FrmGetActiveForm();
// Get the Pointer to the Field
fld = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, fldID));
// Error?!
ErrNonFatalDisplayIf(!fld, "Incorrect Field Specified");
// Swap handles!
oldTxtH = FldGetTextHandle(fld);
FldSetTextHandle(fld, txtH);
// Clear field display
FldEraseField(fld);
// Draw field display
FldDrawField(fld);
// Free some memory baby!
if(oldTxtH)
MemHandleFree(oldTxtH);
// Return the field
return fld;
}
/***********************************************************************
*
* FUNCTION: SetFieldTextFromStr()
*
* DESCRIPTION: Sets Field text from a String
*
* PARAMETERS: - fldID
* - str
*
* RETURNED: field pointer
*
***********************************************************************/
FieldPtr SetFieldTextFromStr(Word fldID, CharPtr str)
{
Handle txtH;
// Create a handle to the string
txtH = MemHandleNew(StrLen(str) +1);
// If the handle is false...
if(!txtH)
return NULL;
// Use the newly created handle to copy the string info to it
StrCopy(MemHandleLock(txtH), str);
// Unlock it
MemHandleUnlock(txtH);
// Use this handle to set the Text to the Field
return SetFieldTextFromHandle(fldID, txtH);
}
The fact the variable "loses" it's information however, makes me
believe it
doesn't have anything to do with the FldInsert function, so much as
it's
being reset.
