Applying for a credit card with two jobs

[simplyhaving]

I have two part time jobs, each accounts for roughly half my income. I just applied for a credit card that I was 95% likely to get according to a calculator, yet only asked for one of my salaries, even though I ticked a 'I have other income' box.

Should I be combining my salaries, even though it asks for the salary for that specific job?

What would happen if I applied again with different info? That's got to look dodgy!
