Macro not functioning correctly, despite correct code

Hi all,

I have a spreadsheet which is designed to store all of my departments projects. I have a macro on a button which will find any job associated with a specific number entered by the user. I have done the same but to search for words associated, and this works fine, however the number one only finds those which have a letter incorporated, and not all those containing the number e.g. it will find a job code 12151a but not 12151.

The macro was made just using the 'record macro' function, and sets the auto filter to 'contains x' in the job number colum. My code is as below:

Sub Findjobno()
'
' Findjobno Macro
'

'
Sheets("Projects").Select
Cells.Select
Selection.AutoFilter
ActiveSheet.Range("$A$1:$AJ$39").AutoFilter Field:=3, Criteria1:="=*" & Sheets("Search").Range("F16") & "*", Operator:=xlAnd


End Sub
Any thoughts??

Many thanks!
Helen

Does anyone have any thoughts on this? I think its because the find function mustnt count numbers alone, but I'm not sure how else to do it!

Any help much appreciated
