Error in FPGA mode due to mismatch between source and sink

[fuzzywaz]

I am unable to do data acquisition using VI in FPGA mode since I'm getting an error which IN unable to comprehend. The error is : Source(which is the analog channel) and sink(which is the subtract operator) are of different type. I have already tried changing the data type to fixed. I have tried typecasting too but am unable to correct the error. As u can see the broken line from the analog channel to the subtract operator is the cause for error. How can i correct this?

I think you forgot to post your VI / a screenshot?

Here it is !

Looking at it - I think your Mod1/AI0 and Mod1/AI2 are missing from your target?

Do you have the VI open in a project, placed under the FPGA and are there two analogue inputs configured with those names? If you re-named them, you might need to re-link them to the names in the project (click and select the I/O).
