Numberfield to time in Crystal 10 - crystal-reports

Question

I'm new to crystal so please excuse me if this is a stupid question. I've got a database field in Sage ERP which is the time, stored as a GMT time, the field type is number. So for example the data in the filed will be 8461110 (08:46) or 13021054 (13:02). Now in crystal I need to convert this field to time because I need to select data between 2 times. I've struggled with this yesterday for the whole time, but no luck.
I've created a formula field with the following code but the result I get is 00:00:00
Local NumberVar TheHour;
Local NumberVar TheMin;
If Len(ToText({ICHIST.AUDTTIME})) = 8 Then
TheHour = ToNumber(Left(ToText({ICHIST.AUDTTIME}),2))
else
TheHour = ToNumber(Left(ToText({ICHIST.AUDTTIME}),1));
If Len(ToText({ICHIST.AUDTTIME})) = 8 Then
TheMin = ToNumber(Mid(ToText({ICHIST.AUDTTIME}),3,2))
else
TheMin = ToNumber(Mid(ToText({ICHIST.AUDTTIME}),2,2));
Time(TheHour,TheMin,00);
What am I doing wrong, why is the result 00:00:00?

Problem is you are missing this :. In crysal reports whenever you want to assign a value to a variable syntax would be :=. So your formula will be
Local NumberVar TheHour;
Local NumberVar TheMin;
If Len(ToText({ICHIST.AUDTTIME})) = 8 Then
TheHour := ToNumber(Left(ToText({ICHIST.AUDTTIME}),2))
else
TheHour := ToNumber(Left(ToText({ICHIST.AUDTTIME}),1));
If Len(ToText({ICHIST.AUDTTIME})) = 8 Then
TheMin := ToNumber(Mid(ToText({ICHIST.AUDTTIME}),3,2))
else
TheMin := ToNumber(Mid(ToText({ICHIST.AUDTTIME}),2,2));
Time(TheHour,TheMin,00);
