The string is non-numeric revisited

[gearworld]

Hi,

I have this error when printing via
CrystalReportViewer

And what I really don't understand is that, the Field that the error message is talking about is a string field so I really don't understand

and also, it stops right at the first line where I'm trying to see if this field is null

here's the first line of the formula

if ISNULL({Qry_Rpt_Prevision_Achat.COMMENT3}) then
""
else
...

I don't know what to do with this. really need help on this.
Thank you

This doesn't seem to work

StrEoqValue = "3"
cDbl(Mid (StrEoqValue, StartPos))

A get the error with this. WHY ?
