Excellent help guys. Compiled with the && so I learned something new today....... but now I just get 16 on Humidity and Temp. I have a 10K pull up resistor on the DATA pin of the SHT71, and the leads are about 5cm long. I found that the program stops here:

ReadSensor: gosub TransferStart : gosub WaitSensor
shiftout dpin,cpin,0,[Sensorcmd\8]
input dpin : cpin = 0
while dpin = 1 : wend
cpin = 1 : pause 1 : cpin = 0
while dpin = 0 : wend '<-----------------program stops here
so obviously the Data pin is not doing what its told to. Any more ideas out there???
